Good, pure, unpolluted water is number one . But having said that, the WHO have declared green tea to be one of the healthiest things people can consume, probably because it is high in anti-oxidants.

Keep drinking the green tea - it is as close as you will get to drinking from the "fountain of youth", and may help in deterring certain diseases. Actually, both green and black work equally well. Most bottled teas in China have nearly the same amount of antioxidants as fresh brewed tea, but they are higher in sugar.

Both tea and water can make no harm to man unless it is beer and other  cold drinks with lots of harmful chemicals.

Actually, Josephine, dark beer is a good source of antioxidants as well. One is hard-pressed to find good dark beer outside of 1st tier cities though. I have to go to the one German restaurant in my city to get it. Now that I'm thinking about it...

Quinn, you da man!. Water and tea? That stuff will rust your pipes!

Beer and snake (cobra wine) will make ya live forever!
