The doctor says, “Ole, all you need is some exercise. I want you to walk ten miles every day. You give me a call in a week and let me know how you’re doing.

So, a week later the phone rings and the doctor answers it. A voice on the other end says, “Doc, dis is Ole!” The doctor says, “Hello Ole. Have you been walking ten miles every day?” 

Ole says, “Yes” 

The doctor says, “And has your sex life improved?”
