Why do Vegans.......?

[Louth]

Excellent point JR but my next door neighbours are both vegan and have brought their three kids up vegan also.
None of the kids have ever tasted meat - two of them are pescatarian.
They are all skinny and sallow in complexion.
I know it’s a lifestyle choice but ultimately it’s not natural and can’t be good for them.

Why can't it be good for them?
Should they be eating the shite most people eat?

What's wrong with skinny and sallow? Does obesity work for you?
