Here I thought it was hard work and hard play for more than 73 years is what wore out my knees...
Hard work - such as carrying a heavy materials will do that for you.
According to a surgery lecture I that attended, each pound of overweight places an additional 8-pounds of weight on one's knees.
Being overweight also increases your chances of osteoarthritis in the knee, a common and often disabling form of arthritis that wears away the knee's cushiony cartilage. Excess pounds also cause existing arthritis to worsen more rapidly. According to the CDC, two out of three obese adults suffer from knee osteoarthritis at some time in their life. . . . from: WebMd
Hard work won't just make one stronger, it will wear out one's body parts too.
