Keep Kids Healthier. Get a Pet.

A new study shows that kids who have pets tend to suffer less from stomach bugs. Apparently, the frequent exposure to low levels of pathogenic organisms strengthens the immune system and makes it less likely to succumb to gastroenteritis. I guess that's true. I was sick all the time as a kid, but rarely from stomach upset. And to this day I have a cast-iron stomach--knock on wood. Now I'm counting on Bella and Twyla to keep me free of heart disease. As much petting as they demand (and get), I should have the heart of a 20-year-old.
