There has been a lot of talk here on getting ill. So I wanted to offer some advice for boosting your immune system. During the winter when I take a shower I will change the temperature of the water dramatically, I will turn the water all the way down and deal with the cold for a few seconds and the turn the temperature all the way up for a few seconds. Do this 3 or 4 times and your bodys immune system will be boosted for the day. It works!
