Life is very mysterious. There are lots of things that are unexplained and since my childhood I could never figure out. For instance, I always wondered why old ladies have short and curly hair. My grandmother has short and curly hair and all her elderly friends also have. Look around and you will notice what I'm talking about. If they have long hair they are probably hipsters, activists or vegan old ladies so they are exceptions to the rule and not considered plain old ladies.
Yesterday night I kept thinking the whole night why old ladies have short and curly hair and I had a moment of "eureka". As old ladies get older the gravity effect pulls their entire body weight down with exception of their hair which grows in opposite direction of the gravity force. This effect is still unexplained but hopefully one day science will figure this out.
Below there's a diagram for what I discovered:
A = AGE
H = HAIR CURLINESS
G = GRAVITY
I know I'm far from being a genius and that this idea sucks but if you think about this it kind of make sense. Just take a look at your grandma.
