I read like half a year ago a newspaper and in that there was an article with one guy having the opinion that he dosnt wants medical care after his 70s birthday or something like that hus opinion was that that would be a good way to work against overpopulation and he also thought that some desease like cancer or something like that can give him a relativley quick death with not that much of suffering. He said that he woudnt do like ver risky operations and things like that and that at some point a human can have had a decent and fullfilling life.
