A lot of people like to mention that suicide is irrational, but I disagree.
I should clarify; I am not saying that it is rational (although I’ll get to that in a bit); I’m saying it doesn’t matter either way.
Is smoking rational? What about eating pizza or drinking pop or shooting heroin? What is really all that rational about a lot of things people do every day. And every one of those things can be rationalized, and often is, by the people who do it. Have you ever successfully gotten a smoker to quit by saying “smoking is irrational”? I doubt it.
