Mine are too numerous to list, but some of the highlights:
I can hear very well and have a knack for analyzing what I DO hear.
I have the ability to smell where you have been, what you have eaten and what is ailing you, sometimes - nose like a dog. It is a gift and a burden.
I have a cast iron stomach.
I can grow a longish beard that random strangers often compliment.
I can shoot a handgun better than the average policeman. (contests have proven)
I seem to be able to calm animals who are in danger of injuring themselves.
I can grow almost any plant to maturity.
I am almost the coolest man alive. "Dos Equis, por favor!"
