Nick Diaz is the wisest fighter in MMA (why hes a vegan)

Dude explains why he's vegan.
Reasoning is on point.
you are what you eat.
if you eat unnatural shit, you will be unnatural shit.

if you eat natural, you will be natural.
when you do something good in something you've never tried...
one might tell you "dude, you're a natural"
in other words, natural = good... unnatural = bad.

EDIT: yes... the animals we consume are unnatural because they inject them with shit for them to grow bigger so more food to give out.
