​There was a dog 11,000 years ago that had cancer. But the nature of cancer causes the cells to stop living for the organism and start living for themselves, growing, making copies, and evolving. Our ancient dog bequeathed its cancer as a hereditary disease carried by future cancerous cells that would form, grow, and evolve in future dogs, generation after generation. One particular pup’s cells lived through generations of dogs. It means that today, there are still living cells of the one exact dog that died a thousand years ago, a single-cell dog.

​Older adults who own a dog are half as likely to experience disability-related problems as their age advances.

The skin on the elbow is thicker than the rest of the body. Tough skin has fewer pain receptors. This is why we barely feel a thing when we pinch our elbows.

​All of us have probably witnessed or experienced bullying when we were younger, and our sensitivity to it was much higher than it is now. Young adolescents may be angrier because they don’t know how to properly analyze and share their feelings. Their hormones during puberty can affect their mood greatly, and they can’t really manage big feelings, such as anger, like adults can.

In a way, time somewhat snatches the anger in us. Older people use their past experiences to cope with anger better. They also often end up living with fewer people and engage in fewer life events, with fewer triggers in their lives.

​Although we feel less fear and anger as we age, our sensitivity to spot happiness stays the same and slowly accumulates as we age. That’s probably why children are so excited to go to their grandparents’ house!

Older people also have a different mental perspective when it comes to aging. The more aware they are that they have a little time left, the more they tend to squeeze themselves into situations that include positive emotions and get rid of negative ones.

​Although it seems logical that older people might be more worried due to their health problems and fewer social relationships, they’re actually way less worried than young adults.

They are fully aware that they change as they age, making them better able to cope and accept who they are — which leads to less worrying. However, if it’s hard for them to look on the bright side, they then use emotion regulation strategies to properly lessen those distressing feelings.

​While a nice A/C would solve the heat problem right away, if that isn’t available, you can start by keeping the curtains or blinds shut. This way, you keep the bright sunlight out and your interior spaces will be cooler. It’s a good first step that might also save you some money on utility bills.

​Getting a fan to help you keep cool is the best and easiest choice for anyone. However, when the environment you’re in is extremely warm, the air from the fan will also be hot. In this case, what you can do is place a bowl full of ice in front of the fan and sit across from it. The warm air from the fan will start getting cooler after uniting with the ice.

​Most people do their shopping by traveling in their cars, but a closed vehicle can reach more than 200 °F (93 °C). You can, of course, blast the A/C, but that will eat up a lot of your gas. That’s why you’d better go shopping early in the morning when your car is still cool. Doing that activity later in the day is not a good idea, as the car will have gathered all that heat from earlier in the day.

​Sugary soda, caffeinated drinks, and energy drinks will lead to dehydration instead of helping you cool off. The best thing you can drink is cold water, even if you don’t feel thirsty. This is because high temperatures make you sweat and, therefore, lose water from your body. If you don’t replenish the lost hydration beforehand, you could face a severe dehydration later.

​While many people go to their nearest gym, which usually has A/C, others choose to exercise in the open air. Whether you enjoy running or doing yoga at the park, you should leave those activities for after the sun has gone down or early in the morning. This is because exercising in heat puts extra stress on your body and makes it increase its core temperature. Exhaustion, heat cramps, and heatstroke are some of the illnesses you might face.

​Wearing sunscreen is vital, even if you’re just going out to your nearby store to grab a bottle of water. But it’s not the only protection you need, since a hat can also become your best friend. However, if you feel like it’s not enough, you should think about carrying an umbrella. The shade it provides protects not only your head, but also your entire body.

​Many people can’t eat the same amounts of food during the summer, and heat is to blame. The best dietary advice on the matter is to eat lots of small meals during the day instead of 1-2 large meals. Also, it’s best to opt for foods full of nutrients and, more specifically, fruits and vegetables that have high water content. You might need to avoid sugary items that contain nothing but empty carbs.

​The problem with dark-colored clothing — especially black items — is that it traps heat from the sun. That’s why it’s advised to switch to lightweight, light-colored garments that reflect the heat and sunlight. Also, loose clothes that don’t hug your body seem to be a much better choice than form-fitting clothes that trap heat and make you sweat.

​A study shows that caffeine impacts how much you spend and how many items you are going to buy. During the experiment, people who drank a cup of coffee spent 50 percent more money and bought about 30 percent more items than those who just had decaf or drank water. Caffeine releases dopamine in the brain. That’s why we’re so excited and why we are more eager to make impulse purchases.

​The reason is very simple. If you shop when you’re hungry, everything will look too appealing, so there is a better chance that you’ll buy something you won’t need. To avoid throwing all the spoiled food away, just make a habit of shopping on a full stomach. This way, you will be less ambitious about what you’ll be able to eat.

​Many people use envelopes for this purpose. But if you prefer a locked safe or a money box, use them instead. The main thing here is to stash money away, out of sight, and to not think about it. You can start with very small sums of money, like one or a few dollars one week.

Next week add 2 dollars or more and so on through the end of the year. This way, you will have more than $1,300 by Christmas — that’s enough to make your friends and relatives happy with a lot of fancy gifts.

​You see, psychologically, it is much easier for us to just swipe a card rather than to part with cash. The thing is that when we take a look at our money, we’re more aware of its value, and we get more of a psychological impact from making a purchase with it.

It’s way different from a credit card. So it’s better to go shopping with a certain amount of cash with you. In this case, you will stop immediately when your wallet is empty and avoid spending more than your budget can afford.

​Just choose the most comfortable day of the week and only go shopping on that day. Give yourself some limits as well, so you don’t throw all your money away in one single day. This method will help you to control your spending better, and you’ll save a lot of money in the future. Just try it and find it out for yourself.

​The bread you buy in a store stays fresh for up to 12 days. And that’s only when you keep it tightly sealed in the fridge. Homemade, or bakery, bread stays fresh for only 5-8 days when stored in the same way. So, if you see that you’re not going to be able to eat it within that timeframe, seal it separately, and put it in the freezer.

Then you can toast it whenever you want to make a sandwich. This way your bread can last from 3-6 months, which will prevent you from having to buy fresh bread all the time.

​Drinking water before or during meals really does make you feel fuller. So if you want to not only save some money on food but to lose weight as well, a large drink is the solution. To lose an extra 4 lbs (1.8 kg) over 12 weeks, all you have to do is drink 500 ml of water with a meal. The amount of money saved will depend on how much you usually spend.

​You can make a monthly report, but the more impressive the sum, the better. So try to count how much you spend every year on ordering food online. Tape it somewhere, so you can look at it as often as possible. This reminder will make you spend less and go shopping instead of sitting home and waiting for a delivery man.

​Just make a rule for yourself to not buy any more groceries if you still have some fresh ones in your fridge. Plan every meal and cook everything by the next shopping date. It is also better to plan ahead. If you’re tired of throwing food away every week, this will be a better option. And your wallet will only thank you for that.

​For instance, in theaters, consider seeing a matinee. They are much cheaper. Also, consider taking popcorn made at home by yourself. This will not only save you a lot of money when going out but will be good for your diet since homemade popcorn has less fat and, consequently, fewer calories.

​Just set your washing machine in cold water mode. This will significantly cut down on water heating costs to the benefit of your monthly budget. Besides, this way it will prevent your clothes from shrinking or colors from fading.

​This time you will be able to not only save on costs but have fun and socialize a bit with your friends and neighbors. Sometimes we get tired of eating the same food every week. So just ask everyone to bring a dish and drink to share in the bounty.

Sharing different food while talking and hanging out together will definitely cheer you up and chase all the blues away.

​In certain cases, this method might also be a solution. Just empty used bath water into buckets or cut off the water and fill up the toilet tank every time you need to flush the toilet. Anyhow, it’s another way to pay less than usual for water.

​Most of us would exhale onto our palms to check if our breath smells okay, but it’s not as effective as licking your wrist with the middle part of your tongue and smelling it.

​To prevent mold growth, you can store your pickles upside down in order for them to be fresh for a longer period of time.

​It’s easier to clean it this way than by using napkins or anything similar, so you won’t accidentally press the keys.

​Rolling them will save a lot of space in your luggage, and it prevents wrinkles from forming on your clothes.

​After letting your gel polish dry for about 1 minute, dip your nails in a bowl of ice water. You can also keep your nail polish in the fridge for both faster drying and better results applying it.

​If your beverage is at room temperature, and you’d like it to be cold, this is a great and easy way to get it colder faster.

​Yoga mats are water-resistant and quite comfortable. You won’t have to feel the cold bathtub or wall anymore when trying to relax.

​You will need to put on thick socks, get into your shoes, and blow hot air on them. Then let the shoes cool down while they’re still on. It will make them more flexible in no time.

​When our phones charge, they can heat up and cases can wrap up the heat. Overheating might lead to battery damage.

​Lacrosse sticks also work perfectly in this situation since nothing will slide off of it.

​Struggling with messy lipstick? Place a hairpin over your lips and apply the color within it. This will make sure the makeup stays beneath the line of your lips.

​If you find contouring difficult, this trick will make it much easier. Simply use the high heel of a shoe and place it on your face along your cheekbone. Use this as a stencil for a sharp contour.

​Use a piece of saran wrap on your face and apply products like foundation, cream blush, and contour onto it. Then flip it over so the product is on your face. Remove the wrap and blend. You will be left with smooth, shining, natural-looking makeup.

​Simply wrap your abdomen in plastic wrap and leave it on for a while. When you remove it, your stomach will look more toned.

​Using the cord of a robe, place it on your head and wrap your hair around it on each side. Secure with hairbands and leave it overnight. In the morning, remove it, and you will find perfect heatless curls.

​Put a Q-tip between your lips while you apply your lipstick. This will catch any mess and ensure perfect, neat coverage of the makeup.

​On those days when your hair is greasy, but you don’t have time to wash it, try this trick — simply use hair gel to pull it back into a bun, and the gel will create a clean and shiny look.

​You can use this idea for a strong matte lip look. Put a tissue over your lips and apply the lip color, then powder, on top of the tissue. When you remove it, your lips underneath will be ready.

​Paint a line of nail polish on the heel of your hand. Press the top of each nail into it for a quick and simple French tip manicure.

​Dip your nail into liquid eyeliner, and then run your nail outward from the corner of your eye. In one simple movement, this will create a dreamy winged eyeliner look without any stress.

​If you’ve ever spent ages making sure your eyebrows look just right, this tip is for you. Put your fingertip in some eyeshadow that’s a similar hue to your brows. Then run your finger once over each brow. Clear away any mess under and over your brows with a Q-tip, and you’re ready to go.

​Use a peel-off mask around the edge of each fingernail. Paint your nails, and after the polish is dry, peel the mask off, and you will be left with completely neat nails — the mask will catch any mess or mistakes!

​If you’ve ever wanted to cut your hair way shorter but have been too nervous to do so, this is for you. Use a ribbon and tie it in a knot right at the bottom of your hair. Then pull it up so that your hair is folded in half, and tie the ribbon on top of your head to secure it. Immediately, your hair will look shorter!

​Put some foundation on a toothpick. Use this to draw some little dots of foundation on your finger. Then dab your finger across your cheeks and the bridge of your nose for a freckled look.

​There are small openings inside the edges of the eyelids called puncta. These openings help to take tears out of the eye. When you blink, some tear fluid is pumped out of the eye through your puncta.

When the puncta are blocked for some reason, tears will overflow.

​Papillae are mushroom-shaped dots that are scattered across your tongue. You have between 200 and 400 across the dorsum or top of the tongue. Each papilla contains 3 to 5 taste buds and isn’t just to detect flavor, but also temperature and touch.

Thanks to papillae, you can enjoy food and avoid pain and poison. They send information to your brain so your body gets alerted to avoid dangers like smoke, for example.

​A single strand can potentially carry a weight of up to 3.5 ounces (100 grams), while a full head of human hair can hold between 12,345 lb to 18,518 lb (5,600 kg and 8,400 kg) without getting yanked out or breaking.

​Usually, we don’t notice it, but while we breathe, one nostril becomes congested and brings less to airflow. Studies say that on average, nostrils switch about every 2 hours. Also, right-handed people tend to breathe more with their left nostrils.

​Your liver has a unique feature in comparison to other organs. It can regenerate itself after damage. Any liver can regrow to its normal size even after 90% of it is removed.

Normally when we think of human senses, we think of 5 of them: eyesight, hearing, taste, touch, and smell. However, your body is capable of sensing way more than this.

Equilibrioception — a sense of balance
Proprioception — knowing which parts of your body are where without looking
Kinaesthesia — a sense of movement
Thermoception — a sense of temperature
Nociception — the ability to feel pain
Chronoception — a sense of time

​At birth, the average baby’s brain is about a quarter of the size of the normal adult brain. Then it doubles in the first year and keeps growing to about 80% of adult size by age 3 and gets to 90% by age 5. At the age of 25, the human brain is fully developed.

​Yes, it’s a fact that kids grow a bit faster in the spring than during other seasons. A major growth spurt happens between 8 and 13 years of age in girls and 10 and 15 years in boys.

​We’re all relatives and share common DNA, even with flowers. Researchers have found that humans and plants share 18.7% of their genomes with each other. We also share 60% of the same DNA with fruit flies and chickens, and 96% with chimpanzees. We’re even similar to bananas, according to studies, as we have about 50% to 60% of the same genes.

​“Hooded eyelids” is a term used to describe eyelids that have extra skin that folds over toward the lash line. Due to this, hooded eyelids may make your eyes smaller because the space on the lid is smaller.

A problem that derives from having hooded eyes, or hooded eyelids, is makeup application. Because the skin folds down and covers the eye, you may find that it hides most of your makeup underneath. However, there is still eye makeup for hooded eyes!

​Since everything we apply on the lid is going to disappear, one makeup tip for hooded eyes is to apply eyeshadow a little higher, maybe even close to the brow bone. By doing this, eyeshadow is still going to show up when you look straight ahead without any problems. Just blend it upward, and the payoff will be great! You can do this not only with eyeshadow but with any makeup product that is destined to go on your eyes (eyeliner, glitter, etc.).

​Hooded eyelid makeup implies having your real crease hidden behind some extra folds of skin, so why not create a new one. You can create a new crease with makeup like this: over your eyeshadow, apply concealer above the crease (following the shape of your eye), to give the illusion that your natural crease is higher than it actually is. This way it will give the illusion of a crease, without actually being your natural one.

It is crucial to take all the necessary steps when it comes to making hooded eyes look bigger. One way to do makeup on hooded eyes is to highlight the brow bone. It will give a lifting effect, tricking the eye into thinking the skin is more lifted than it actually is.

Bonus tip: Highlighting works wonders on your face, just add a bit of highlighter under the brow bone, on the tip of and down the nose, and on the cheekbones to create an elevated effect.

​Eye makeup for hooded lids also means highlighting your inner corner can be a good idea. When light bounces off that highlight, it will give the illusion of lifted eyes, despite them still being hooded. To achieve this look, simply take a look at where your inner crease starts, and apply some sparkle starting from there.

​One tricky thing when doing makeup on hooded eyes is applying eyeliner. Do not fret, though, there is a technique that might just help you: “bat wing” eyeliner. The name says it all.

When applying eyeliner, look straight ahead and draw your wing on the lid space that is exposed. Afterward, fill everything in, and the finished product is a wing that can be seen when looking ahead, and when you close your eyes, a “bat wing” can be seen.

​Priming is a crucial step in a general sense, however hooded eyes need priming due to the fold transferring makeup on the hood itself, which, when you open your eyes, could create a mess. Not only that, but priming creates a smooth surface for you to work on and ensures that your hooded eyelid makeup will stay in place no matter the weather.

Priming can also make eyeshadow pop more, whereas putting eyeshadow directly on your lid may not work since the color of your natural lid may not be even.

​Eyeshadow for hooded eyelids can be troublesome, however the trick is to look forward the whole time. This way, even if you have your eyes open, your hooded lids won’t cover any of the work you did underneath.

Jaleesa Jaikaran, makeup expert, says that: “You want to look forward when you’re doing eyeshadow for hooded eyes because if you look down or if you do anything else, you’re really not going to see the effect when the eyes are open. So try to always look forward.”

​Matte eyeshadow is a great makeup for hooded eyes. Use a matte eyeshadow to create a shadow above your natural crease. This is going to trick the eye, and make it look like your crease is higher than it actually is. Not only that, but it will also make it look as if your crease is fading backward, making your eyes look more open.

Pro-tip: Keep those darker shadows on the outer part of your eyes, and the lighter ones closer to the inside of your eye.

​Instead of blending with circular motions, do your eyeshadow in straight horizontal lines. This is called the “straight-line” technique. Blending eyeshadow straight across instead of curving it around your eye will give the illusion of more eye-space on your hooded eyes. When doing makeup on hooded eyes, it’s important to deal with your eye space correctly, not blending past the point where your lid meets the end of your eyebrow.

​The egg compartment on the refrigerator door is not ideal because it is the warmest part of the fridge and is constantly opened and closed, which could compromise the quality of the eggs. According to food safety experts, there is a proper way to store products. Eggs should be kept in a cool place and inside their cartons. Always check the temperature of the refrigerator (it should be 39 °F or colder), and the freezer (0 °F).

​Some people believe that razors are easily disposable after only a few uses because the steel material rusts quickly, but there is a way to save money and extend the usage of the razor. Do not leave the razor in the bathroom or any other moist area because bacteria will grow on it, and steel does not go well with moisture. Keep it dry and away from the bathroom to ensure that it does not rust and that it lasts a long time.

​To keep bread fresh for weeks, place slices in a separate plastic bag, then remove all the air and seal it tightly. Air and moisture will no longer be able to enter and cause mold to grow. Then place it in the freezer, and it will last for up to 3 months or more.

​Most people wear sunglasses, especially when it’s sunny and warm outside. When the sun goes down, there are numerous ways to store shades. People usually keep them in the chest area of their shirts, and some keep them in their pants pockets. The best place to store them is inverted in a chest pocket, which will protect the shades and keep them safe without damaging the lenses.

​Condiment food jars, like pickles, could also last a long time by storing them upside down in the fridge. In this way, mold has a hard time growing inside. According to an expert, “By turning the jar upside down, that surface where a mold may have landed when you opened the jar is now squashed against the lid without much air, which will make it more difficult to grow.”

Put the cream in the bottom of the cup and pour the coffee in. Thousands of spoons will be saved from the dishwasher. Hundreds of stir sticks will be kept out of landfills.

​Long wax wicks create a large flame that quickly depletes the wax, but if you cut the nib every now and then, it will create a small fire that will suffice to keep the room smelling good while also saving a lot of wax for later use. This will save you a lot of money because you can reuse the glass container after you run out of wax.

​My summer hack is coffee ice cubes. I make a tray of coffee cubes for my iced coffee. One cup of coffee makes one tray. Game changer, no more watery iced coffee.

​The loose end of the toilet paper should be facing you rather than the wall for easier use and to prevent bacteria from lingering on the paper when not in use because it is facing the wall.

Then squish it horizontally until it takes on an oval shape in the center. This is to make it more difficult for the toilet paper to rotate because people tend to grab the toilet paper, and it easily rotates, resulting in waste. More controlled rotation results in less waste.

Saying “thank you” instead of apologizing for things that don’t need apologies. I’m a chronic apologizer, and it’s helped a lot. For example, if I have a bad day and vent to my husband, instead of saying “sorry for venting and bringing down the mood,” I’ll say “thank you for listening and being supportive.” It puts a much more appreciative and positive light on your relationships!

​It is critical to season a new pan with oil. Spread the oil around the pan’s edges, then place it in the oven until the heat lets the pan absorb the oil. Then set it aside to cool and wipe away any excess oil from the pan after it has cooled.

This allows the oil to fill the gaps and pores of the pan, so it will have an even cooking surface. When cooking, things won’t stick anymore.

​While squatting, there are 3 points on your foot that you want to apply the most pressure to. It’s the point right before your big toe, the point right before your little toe, and your heel. If it’s hard for you to understand if you are applying the right pressure on these points, you can just take your shoes off. This will give you the ability to feel the pressure a lot easier, from the ground straight to your feet.

​The best shoes you can wear for lifting weights are, of course, weightlifting shoes, like the ones professional athletes wear. However, a flat sole shoe will do if you don’t have them, or you can’t spend extra money to get them. Also, barefoot weightlifting has become very popular lately, with its fans saying that it helps with stability and balance.

On the other hand, you don’t want to keep your running shoes on while weightlifting. They are great for walking and running, but the gel or air-based sole won’t help maintain a balanced footing.

​There are 6 different ways you can perform a bench grip, but one of them is simply wrong and dangerous. This is when your thumb is placed underneath the barbell on the same side as your fingers. This makes it a lot easier for it to slide and fall on your face or your chest and injure you. And while it has some benefits, it is advised that you not use it.

However, you should feel free to get a good grip on the barbell and decide whether you want it to be close, medium, or wide. It depends on what part of your arms you want to concentrate on the most. The other 2 grips that you can try are the reverse grip and the neutral grip, which are usually used on the Swiss bar.

​One big mistake you can make during this exercise is to let your shoulders roll forward and your chin go above the handle. What can happen here is a shoulder rotator injury, since there is too much strain on that area. Instead of that, you can put your chest forward and try to reach the handle with it. This will keep your shoulders back and give a nice curve to your back, while your chin stays at the level of the handle.

​Planking is an exercise you either love or hate, but most exercise programs include. One of the mistakes you can make is to keep your buttocks lifted and your belly hanging low. This is usually accompanied by the person lifting their head and looking up instead of looking down.

So, it’s important to keep your head down and maintain a straight posture. Don’t arch your back, either, as this will put too much strain on your spine. Just tuck in your buttocks a little and squeeze your glutes.

​If you think that your body and arms need to be perfectly straight, then you are 100% wrong. Your elbows should be flexed between 20-30 degrees, and you shouldn’t lift the weights higher than your shoulders. Your knees should also be flexible and your torso slightly tilted. You should avoid lifting the weights over your shoulders and close to your head, since that will do more harm than good.

Another useful tip would be to pause for a bit when you reach the top of the movement. This small detail will help you shift the focus from the trapezius muscles in your upper back to your shoulders.

​This exercise is quite popular and almost everyone, whether they train or not, knows about it. However, there are ways that you can mess it up and even cause injury. The most common mistake is keeping your arms too far from the rest of your body, which can cause stress to your muscles and joints. The best placement for your elbows is at a 45-degree angle from your torso.
