Low protein, low calorie, low activity, low fun lifestyles do prolong life. We've known that for years. This isn't a life extensionist forum however, so fuck off.
I don't want to castrate the quality of my life just to live another two or three pitiful years eating bird seed and staying indoors to avoid any accidental fun and enjoyment. If that's up your alley, go buy some organic qiunoa and stick it up your rectum for a low glycemic treat, asshole.
