This is not True..I know of many vegans who looks better and have more energy now than they did before. One vegean is in his 70s and looks great..he does yoga, and works 8-12 hours a day and is still going well..another looks in his 30s and he is in his 50s..I have seem one lady who is a vegan she looks old, not sure why she is the only caucasion the others are of asian background.
