I have many friends, mostly but not all female, who are vegetarian or vegan. It is amazing to me what maladies people will endure and convince themselves that they are "healthy". Finger nails that rot, thin and brittle hair, poor vision, rotting teeth, dry skin, constant tiredness, weakness, brittle bones, cuts that don't heal, I could type for lines and lines and lines...
It's as if they've been convinced that all of the above is a normal state of human being.
I'm glad I eat meat.
