Some Vegans do drink alcohol since most alcohol is already naturally vegan although some types of alcohol contain animal products but most alcohol is animal free and vegan.
Vegans will sometimes live between 6 years to 9 years longer than a meat eater.
However being a vegan doesn't mean you'll always live longer than a meat eater.
Most vegans do tend to live longer when compared to meat eaters.
Vegans live on average of around 6 to 9 years longer than meat eaters but it's not really because the vegan is not eating meat.
Most vegans who eat strictly vegan foods are usually more health conscious and get more exercise and work to keep their bodies healthy.
Even those people who eat meat as well as vegetables can still live a good long life as long as you stay healthy and active.
Get plenty of exercise lose weight if you're overweight, eat other healthy foods, drink water etc and you should live just as long as vegans even when you eat meat.
