How to impress your Doctor

During my physical examination today, my doctor asked me about my physical activity level.
I described a typical day this way:
"Well, yesterday afternoon, I took a five hour walk about 8 km through some pretty rough terrain. I waded along the edge of a lake. I pushed my way through scrub, I got sand in my shoes, eyes, and hair. Avoided stepping on a snake. I climbed several rocky hills. I relieved myself a couple of times behind some big trees. The mental stress of it all took a toll, so it was nice to wind down playing poker and having a few drinks with my mates."
Inspired by the story, the doctor said, "You must be one heck of an outdoors man!"
"No," I replied, "I'm just a terrible golfer."
