Note that heat shock hormesis and calorie restriction hormesis (which may involve the same underlying mechanisms) are demonstrably good for you. The science backing those forms of enhanced bodily health are good: a little damage and adversity provokes the body into much greater clean-up and defense efforts, with the net result of increased health and longevity. See: http://en.wikipedia.org/wiki/Hormesis http://en.wikipedia.org/wiki/Hormesis As other posters point out, the data for radiation hormesis is lacking in comparison. However, it's not an unreasonable hypothesis given the reaction of mammal biology to other types of low-level damage.
