Take a walk

I've spent the last two weeks sick with the latest flu going around. Last evening I talked with my son and he had been sick as well. The main difference is it only lasted a few days for him. As we talked, I was thinking about why he would be healthier than me, besides age. In the course of the conversation he told me about several of his friends who had been ill. The common theme that seemed to run throughout how long someone was sick had to do with walking.
