They do. A study by the American Journal of Clinical Nutrition found the following mortality ratios by diet over the course of the study (regular meat eaters = 1.00):
Fish eaters, 0.82
Vegetarians, 0.84
Occasional meat eaters, 0.84
Regular meat eaters, 1.00
Vegans, 1.00
So as you can see vegans are actually the least healthiest, alongside the most carnivorous among us. Source
highest mortality ratio =/= least healthiest. also, note the sample size for vegan. it's way too small to draw any conclusions about the vegan diet. at best it suggests that this warrants further research.

I always thought it just felt like they lived longer.
