At work I have a few chicks who are the vegan, farm to table health nuts. Don't drink bottle water because of the chemicals in plastic, only eat organic veggies and grains etc...
The one thing they also have in common is that they're always sick. Constantly blowing their nose and look clammy and pale. They have mushy shapeless bodies and just seem tired all the time.
I know Johnny Falcon will blast this but I rarely see a vegan health nut that doesn't seem lethargic and constantly sick.
