Gene Stone spent several years of investigating why some people never get sick. One thing he found was that all of them consciously follow a preventive regimen with consistency and conviction.
He interviewed more than 100 people who seemed never to fall ill, and wrote about the 25 techniques that seemed to work best.
According to ABC News, here are some of the best techniques:
- Chewing on a clove of garlic
- Starting off each day with brewer's yeast, which is rich in protein and B vitamins
- Eating less -- studies suggest that reducing daily calories by as little as 25 percent could have life-lengthening effects
- Vitamin C
