Just out of curiosity, am I crazy by not regularly drinking coffee? Is there some benefit from it that I'm potentially missing out on, or will I perhaps be in for a rude awakening in a few years because of my lack of it? I do recall reading somewhere that people who did drink coffee vs those who didn't had better odds against things like Alzheimer's disease, so maybe that's one benefit..?

I'm completely serious in asking - I passed my 30th birthday a couple weeks ago and even for the past few years my aunt and others I know always ask how I get by without it. I have no aversion to it and would drink it if I needed a boost due to a poor night's sleep, but that would be maybe once every few months at most. This doesn't make me special at all so I'm not boasting or anything - the only reason I don't drink it(other than fear of stained teeth) is because I don't want to develop a need* for it, i.e. "I can't start my day until I've had that first mug". That would hardly be the worst thing in the world, but I'd just rather avoid it if I could.

For what it's worth I typically get 6-7 hours of sleep each night, and I exercise several times a week.

*I would typically use the word addiction, but that might be a little too strong given the context
