I've been reading about cholinergics which improve cognitive abilities, and I discovered an interesting fact. Most nerve agents work like cholinergics! The problem is that nerve agents (sarin, VX) are toxic, so they in fact cause brain damage, which in turn kills you, unless you administer a strong anticholinergic such as atropine.

I just thought it's interesting that the same action used to treat cognitive impairment is used to kill people.

Please, don't use this as a guide to improve your cognition!
