Rizks Kutty goes to see his doctor: "Doctor, my sex life is terrible, absolutely terrible!"

The doctor examines him, and says, "You need exercise. I want you to run every day, two miles a day. It'll improve your heart rate, your general well-being, your self-image, your libido. Then call me in a week".

A week later, Rizks calls his doctor, says "Well, Doc, I've been running every day, two miles a day, just like you said".

The doctor asks him "So, how's your sex life?"
Rizks says "I don't know. I'm fourteen miles from home."
