I've seen intelligent people, who are experts in their domain, fall from grace through age or illness.

Once critical thinkers, now vulnerable and gullible.

I wouldn't be so harsh.

You're right, of course. I was excluding people who really aren't at fault. When someone's brain turns into a vegetable he's not capable of thinking things through, so he can not be responsible for the stupid things he's doing.

Doesn't change the rest, though.
