Every man? Glad to meet you, Butterbean.
Men armed with knives and clubs? Glad to meet you, Bruce Lee.
Will you be able to do so in your 60's? Glad to meet you, Joe Foreman.
You are so full of it. You think you can take on the world. You'd probably fold after first punch in most scuffles. Add to that the fact that Mr. Selfish (you) only seem to care if *you* are safe. What about slightly-built men and women? What about the elderly? Just throw them to the wolves, right?
Go back to England. We don't want your sort here.
