A man visited his doctor, and the doctor checked him over before commenting, "It looks like you get a fair bit of exercise".
The man replied, "Oh yeah, in fact just the other day I walked five kilometers over rugged terrain as I climbed over rocks and trees. I also waded along the edges of a lake, pushing my way through tall thistles, and even slid down sandy slopes while getting sand in my eyes".
The doctor was quite impressed. "Well, you certainly are a dedicated outdoor enthusiast".
"Oh, not really", the man replied. "I play golf".
