I've officially decided to become a vegan! No more animal products for me. 
Why not? Meat is good.
Meat /is/ good, but this is for dietary purposes. Plenty of vegans cut animal products out of their diet just to be healthier.
It's all about the quantities. Vegans don't look very healthy to me.
If you do it the right way, a vegan diet can be really healthy. It reduces the risk of chronic disease, in some cases.
