Are all vegetarians/vegans one day going to be wiped out due to lack of nutrition?

OH..............is that why we live longer, and lack major percentages of cancer and impotence cases? Why my stomach ulcers have healed and my stomach disorders have ceased? Ignoraaant. Stop copying and pasting things that vicious meat eaters write in defensiveness because they are addicted to eating carces. EWWWWWWWWW DISGUSTING!!!!
