Like Ryan says he looks great for 22. I wouldn't worry about the grey. Horses are like people and dogs in this respect. Some go grey early. My dogs muzzle has started to grey at age 5. My last dogs muzzle greyed at about the same age, 5 or 6, and she lived to be 15 which is great for her breed. My old quarter horse was 29 when he left and he had no grey at all.
