Want me to send you a copy of BOTH my statistics AND my psychology book? The part where it says that an episodic example is not the general case?

I know a 92 year old smoker. Therefore all studies which declare tjat smoking cuts down on your life span becomes bullsh*t. Right?

Nothing personal, I enjoy the intellectual exercise of arguing, but episodic examples prove absolutely nothing.

Just because it has happened before doesn't mean he's right and I'm wrong.

Furthermore, we could re-interpret your example to mean that someone with the inclination to do violence might take up drinking in order to sucker punch the guy he doesn't like. Drinking didn't make you dislike him, drinking didn't make you punch him. You dislike him. You got drunk. You punched him. There could be a million other things in between these events that drove you to it, not necessarily the alcohol.
