humans survived here on earth and lived full 80-100 year life spans since the cave men. the average lifetime has gone up because of less war and less disease and more treatments and such for ailments. this has nothing to do with the fact that western medicine is not healthy. western medicine creates a weakness in your body not strength. if you want to live to be 110 thats awesome but you should know the last 30 years you are going to be reading alot and watching alot of tv or whatever. the body breaks down. the spirit does not. do not obey your doctor. do not obey your parents. do not obey anybody. accept their advice and suggestions, get another opinion, weigh out the choices and consequences and then decide for yourself.
