Comment Good/Bad Health is contagious (Score 1) 227
Different populations of bacteria can have an effect on our health, good or bad. Ergo, you want to catch the bacteria of healthy people. Ergo one should have sex and "taste/inoculate" oneself with healthy, thin people. Also obesity is similarly contagious so avoid oral/fecal contact with fatties. This is so classic a concept. Its ironic that people 1000 years ago probably believed this, and in fact it may stand up to science.
