Do you lose 10 brain cells every time you hit your head?

Answer 1

At that rate, if you hit your head every day, in 500 years you will damage enough cells to notice a difference.
Just as a comparison - a boxer will irreparably damage millions of brain cells with each bout.

Answer 2

If when you get hit hurts, you do lose some brain cells. I don't think necessarily 10, though. If can be more or less.

Answer 3

i don't know if that is true or not, but they say that the average person uses what, 10% of their brain? with that much extra, hitting your head seems a bit silly to worry about.
