I've been drinking four cups of green tea every morning - I make it all at once in a Pyrex measuring cup and pour it into a water bottle and drink it through lunch. I haven't been sick since August, knock noggin, and that was when I was traveling cross-country.

I work every morning at an elementary school, too. I use antibacterial lotion every now and then, maybe once a week if someone who is obviously sick touches me, but most of the time I just rely on handwashing and green tea.

Oh, and I'm eating an apple every other day or so at snack, too, with my daughter - easy to transport and she likes them.

I think it's the antioxidants in the green tea, though, that are boosting my immune system.
