20 Questions We've All Asked Ourselves (But Never Bothered To Find Out)

8. Why Does Hair Turn Grey?

Have you gotten to that time of your life yet? When you're brushing your hair and you're met with it, looking straight back at you. Oh god, it's a grey hair! Don't worry, it just means you're now officially old, we're all going to get there, at least you're not bald yet. Perhaps you could pull it off gracefully like that guy from Catfish the TV show? Now, there's a common misconception when it comes to grey or white hair, when you say your hair is turning grey, you're wrong, so wrong, stop being wrong, readers. I'm not saying you're not going to be grey soon, don't worry, you are actually losing your colour, it's just that it was grey to begin, which is the base colour of all hair, you see? Pigments cells at the base of hair follicles produce the natural colour of what we'll call our youth hair, which you'll say goodbye to soon. However, as we grow older more and more of these cells die, your youth hair colour is lost from each hair and your natural grey begins to shine through. Heck, it may even go darker before it gets there, so don't get too cocky if you're suddenly a darker shade blonde, you're getting there, my friend. Don't worry though, one measly hair isn't the end of the world, you're not going to go grey overnight. But you are still going to go grey, so actually, you should still probably worry.

7. Why Does Our Skin Go Wrinkly In Water?

We've already touched on your bathroom antics earlier in the article, but think back to when you were a child and you got out of the tub and started drying that cute little butt of yours down, when suddenly something caught your eye. Your fingers and your toes are all wrinkly and you screamed and freaked out, asking your mum why your fingers and look like grandads' face. She'd laugh and console you, tell you that it was just because they were wet. But then you went to bed, your mum's laughing stopped, she poured herself a glass of sherry and pondered, 'why do our fingers go wrinkly when they're wet?' It kept her up most nights because she didn't know. She just didn't know. See, now you can make her day when you next see her, because you're going to have the answer. The reason our fingers and toes become wrinkled when submerged in water is because our skin is covered in a weird waterproof layer called keratin, apparently, which prevents both the loss and uptake of water. However, that keratin is pretty worn out on our hands and feet because of all that touching and whatever it is you do with them, so water is able to penetrate the cells and cause the wrinkles. The keratin also absorbs water and expands when our skin gets wet, but there is no room for expansion on our fingers and toes, which again causes the wrinkles. Of course, the wrinkles go away when the skin dries, but it's going to take much more than that to get rid of the ones on your mum's face, we're afraid.
