After a long life of over eating meats, I've recently begun to try out being vegan, though I can't commit fully yet.
Really? Why?
It was a personal choice I felt I had to make. I disliked how so many companies treat animals like a commodity instead of living creatures. I still support eating meat, but using humane practices in any animal made product.
Ok. Meat is good. I love steak 
I agree, steak if a fantastic food, but it isn't necessary for survival. In most developed countries meat is actually secondary to survival or health. We just really love the taste!
That is true.
Another benefit of cutting meat in general is that it can reduce risks of some types of disease, such as heart disease. A salad and some exercise can really do your body good!
But do you eat fish?
Fish is another controversial one for vegans. I can't deny that they are an important source of protein for many humans, both in history and in modern times. If you live on an island, you might have to eat fish sometime!
