http://en.wikipedia.org/wiki/Health_effects_of_coffee From that we learn that coffe is linked to increased levels of smoking and lack of exercise -- AND: A May 2012 study by the New England Journal of Medicine found that, during the course of their study, coffee drinkers "who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study."…

> Edit: I should add that no chemical is good for everyone, not even caffeine. Obviously false. It is hard to live without chemicals like oxygen and water (though too much of either can be toxic).

Same goes for proteins, fats, sugars and vitamins. I meant drug, I was writing from a pub listening to Irish music. Sorry about being inexact.

I keep switching between tea and coffee. I like tea more at the moment (green, white, black, pu-erh, sometimes herbal). There just seems to be a wider variety of teas that I can switch between. I don't do it for alertness or withdrawal symptoms as much as I do it for the taste. Coffee to me, while tasting good, more or less seems similar (short of changes in roasting levels).

Fwiw, tea doesn't contain any caffeine - it has it's own methylzanthine, with similar but slightly differenr effects. (It also contains l-theanine).

The importance and effectiveness of caffeine has a lot to do with your job and lifestyle. If you are a mostly sedentary computer worker, the lack of blood circulation from sitting all day is going to make you super tired and slow your brain down. If you're a more active person, either from daily exercise, standing up at work, or a more physically strenuous job you're going to have more maintained energy levels as you…

Another anecdote, this is mine:

I made a change in my lifestyle and I can work faster and for about three times the hours I was working before that.

My lifestyle change is not related to caffeine, I stopped eating lots of carbs and now I follow a keto diet.

YMMV, etc.
