Imagine if you had a friend who was really smart. So smart that during any argument or intellectual discussion you would have no hope of winning the argument.

Now imagine that friend gets sick and his powerful brain turns on him.
That person wouldn't stand a chance.

I have no idea really, but I imagine that depression and suicide are probably like that.
Something in the brain has gone haywire. Why else would an intelligent person with a survival instinct genetically built it, decide not to survive?

I just can't understand this sort of action otherwise.
