the gooks have belife about specific blood types being gooder at specific things like being a warrior or farmer or whatever
but i remember reading some studies a couple years back about dieting based on your blood type, and how you can pass down a different blood type to your child based on your diet, like if you're lactose intolerant, it's apparently your blood type that has issue with it but if you put up with it for long enough that mutation will pass down and your kid won't have the issue with it anymore since their blood type adapted to it or whatever
