Men prefer bitter tastes.
Women prefer sweet tastes.
Which is better?
I prefer the taste of a woman who has been drinking coffee. Is that legal? LOL

The health aspect is marginal - every week a different story about benefits or problems.
I drink strong black coffee all day long, switching to half-caffeine after lunch. I don't think it has ever affected my mind adversely, and I sleep well.
I also like green powder tea, very strong.
It's the same with anaesthetics or alcohol (in the past) - it takes a massive dose to affect me as I'm 'non-responsive'.
It's not what you drink which is the greatest risk - it's the incense, if used. I love it and must have inhaled loads of it. Apparently, cancer is a problem for temple attendants due to the smoke.
There must be a study somewhere of religious attitudes to (and use of) 'indigenous' drugs favoured by different cultures.
I've not heard a Guru speak about tea and coffee at retreats and festivals etc. but I personally see it as a very minor issue compared with alcohol, which can really mess up a person's chances of benefit from any retreat.
