Getting my knees replaced forced me to give up two activities that I had greatly enjoyed, running and skiing. I had never been a runner until I gave up smoking after 20 years of heavy cigarette use, but running then became my new addiction. For several years I was running about 40 miles a week. I ate all the junk food I wanted and stayed lean and strong. I took up skiing in my mid 30's and while I was never competitive, I became fairly proficient. But I was warned by the ortho docs that the prosthetics could not handle the pounding of running, and the twisting of skiing could end up destroying the prosthetics. But by the time I had my knees replaced I could not run or ski anyway so I know I am far better off with the fake knees and able to walk without undue pain and do it for as much as I want.
I was a runner myself, and came to it later in life also. I had always lifted weights, but had unfortunately fallen into eating "like I was going to the electric chair."
I was called in by my boss and told I would be fired unless I lost some weight. (ah, the old values!) So I started jogging and loved it.
Anyway, I ran for years until a knee scope finished my days on the trail. Ten years later, the right knee was replaced.
I retired in '19, and began lifting 3 days a week, stopping only for these hip surgeries.
8 weeks after my first hip, my doctor cleared me for "all activity." I went home, jumped on my motorcycle, and went for a spin. Still a bit wobbly, I was turning left after a stop and fell over directly on my surgical hip.
Other than a huge bruise, and some minor bike damage, it was all good, and I somehow managed to avoid divorce.
