tea is good for health,or cocoa?

I think tea is much better than cocoa.tea is much more refreshing.

i think both of them is good for health as long as we dont consume it to much, i ever read in an article that drinking 4 cups of tea is like drinking 12 cups water, drinking 4 cups tea is enough for a day, coffee also good for our brain, i ever read that the cafein in coffee helps to stimulate our brain that can make us work hard, that's why many people said that drink coffee make us cant sleep because our brain cant stop working
