According to the National Academy of Sciences, you should schedule more time for tea every day. They suggest drinking 20 ounces of black tea daily before you go flying. Their sources indicate that this causes the body to secrete two to four times more interferon, thus strengthening the immune system. If I drink 20 ounces a day I will be floating, but I sure intend to give it a good old try. If I succeed, I should be as fit as Michael Phelps by the time I finish. He’d better watch out in 2012 – and I can’t even swim!
