An elderly man’s doctor asked him about his physical activity level.
He described a typical day.
“Well, yesterday afternoon, I took a five-hour walk about 10 kilometers through some pretty rough terrain.”
“I waded along the edge of a lake. I pushed my way through brambles.”
“I got sand in my shoes and my eyes. I narrowly avoided standing on a snake.”
“I climbed several rocky hills. I had to stop several times to relieve myself behind some big trees.”
“The mental stress of it all left me shattered. In the end, I drank eight beers.”
