Beer
This page contains a discussion of alcohol. I've attempted not to glorify it by any means to people who don't want to drink alcohol, but I'll leave it to yous lot to judge that. Edit as necessary.
Beer is as varied as people. Some are mellow, some are fruity, but some are just downright sickly. The main difference is that people don't intoxicate you, except if you're friends or in love.
It is, likewise, just as gorgeous as people. When taken in moderation, such as a cheeky pint at the end of the week with your pals, it can set you free.
Some people don't dig alcohol for various and complex reasons, and that's totally cool. It's your body, and you choose what to put in it. But for those that do, I'd propose that beer is a perfect drink. It's a bit of fun, it can be tasty as heck, and one or two pints will still leae you with your faculties, generally, though your mileage may vary of course. And, if your water might be infected with nasty germs, the low alcohol content kills them off. Psychedelic!
