I was watching this cooking show a while ago, and one of the cooks was a women that used to teach math.
However, when she was on vacation, she fell on her head, and had to undergo surgery.
From that point on, she no longer understood math.
This made me realise that all that we are, is our brain.
If it gets damaged, we will no longer function well.
A kid that used to go to my school, was in a car crash(Drunk driving), and needed to go to a hospital.
No harm done really, untill a virus infected his brain, and the doctors needed to cut away a part of his brain.
This causes him to stay on his level of adultness(Dont know the word), so he will keep the same level of humor, will never understand why he shouldn't eat pizza and drink Coca cola all day, and will never be any more mature then he is.
He will always be a teenager.
Point is, when you die, your brain, get broken down.
So you will no longer function.
And thus you will just die, the end.
TL;DR there is no life after dead.
