Coffee? What the heck is unhealthy about coffee? No fat, no sugar, no calories. Every health warning about it has turned out to be pure bunk.
I've never heard a religious fundamentalist tell me that dinosaurs shouldn't be in textbooks.
I never have heard that one either. Most of the debate is about the time frame of when they lived not about the dinosaurs themselves.
Not much. Habitual drinkers have a third to a half less renal system disease than non-drinkers, and a few studies have shown unusually potent anti-carcinogenic effects in mammals (though not tested in humans that I recall). Generally though, yeah, unless you have a particular sensitivity to coffee (many of the "side-effects" are actually caused by compounds and stimulants other than caffeine), it is hard to paint it as "bad" for you. Habitual drinkers also do not have the cardiovascular reaction that occasional drinkers do, the body quickly learning to ignore many of the bioactive chemicals in coffee.
So drink up. Don't let the killjoys spoil your fun.
