I know a lot of people will criticise what I say(as they predictably always do) that I'm being a troll yet again coming with a subversive view on things. Anyways, it's a only theory, nothing written in stone, think what you will. Ok, this isn't something I've tried for myself at least not to it's logical conclusion, but I wouldn't be surprised if you already know deep inside which food is good for you. Say if I had to kill for food, I'd somehow have least trouble killing fish. My conscience would suffer if I had to kill a dog, lamb, horse or whatever....or even worse, what some people do as last resort(unless theyre hannibal the cannible). Kill and eat another human being. This by the way is not a very healthy thing to do. Cultures with cannabilism have a lot of strange diseases as a result of it. The same one can also say, be it to a lesser extent of those other mammels that might be tasty to eat, but IMO at least, would be hard to slaughter yourself. Fish on the other hand are well known to be good for you. Countries with a diet rich in fish(like Japan)have a longer life span, and a generally good quality health until quite an old age. But what about insects? They would be even easier to kill than fish. With fish I'd still tend to place myself in the position of the fish that's slowly sufficating to death. Not as much as the above mentioned animals but still....Insects on the other hand, I don't think twice about killing them, could this say something about insects in relation to health? There's an unlimited amount of them, don't require much to feed, multiply very quickly....... Anyone?
