So U think Vegan is healthy?

[Coffee Jesus]

poorer health ≠ don't live as long

LOL, um yes I'm afraid that's exactly what it is. Here's a short presentation by Dan Buettner:

So a person who chooses castration in hopes of life extension is making the healthy choice?

If you want to suggest that meat consumption or diary consumption or fish consumption increases mortality compared to no consumption then they do need to be factored and controlled.

Good, I'm glad we finally agree on this.

--edited to add--

Psychology Today that says 75% of vegetarians in the USA go back to a vegan diet with the average length of time on a vegetarian diet being 9 years. There's no data on vegans going to and from vegetarian diets - however it is possibly quite high as I've seen a number of Youtube videos of vegans who have gone between vegan and vegetarian a number of times.

Okay good point. I have to account not only any who returned to meat, but also for any who returned to vegetarianism. The latter might have occurred more frequently.
Plus, a vegan will be more likely to switch if they are experiencing health problems that could be a result of their veganism.
