Keep in mind that what, around 50% of Americans are overweight or obese. Americans (and Canadians) as a group aren't that healthy, the overweight and obesity rates here are disturbing.

Poor diet, lack of exercise, and malnourishment will all have significant effects on the immune system. It is really ironic that a large percent of people who are overweight or obese are actually malnourished, even with all the food they eat!

If you live a healthy lifestyle and take care of yourself, it's possible to go years without significant illness.
