I think some people cheat on their partners for a reason that's not dissimilar. Kind of a sense of reckless self sabotage, and if it works out okay then there's a resulting elated feeling that comes with survival. And then you keep returning for the anticipation, and the high.

"I think the basic anti-aging diet is also the best diet for prevention and treatment of diabetes, scleroderma, and the various "connective tissue diseases." This would emphasize high protein, low unsaturated fats, low iron, and high antioxidant consumption, with a moderate or low starch consumption.
In practice, this means that a major part of the diet should be milk, cheese, eggs, shellfish, fruits and coconut oil, with vitamin E and salt as the safest supplements."
