Disadvantage

"The average age (longevity) of a meat eater is 63. I am on the verge of 85 and still work as hard as ever. I have lived quite long enough and am trying to die; but I simply cannot do it. A single beef-steak would finish me; but I cannot bring myself to swallow it. I am oppressed with a dread of living forever. That is the only disadvantage of vegetarianism."
--George Bernard Shaw
