As it happens, due in part to my IT career, this year I spent time on a $$$$ Physical Therapy cycle machine which tapped the patient's output to run the display. That is, if the patient made at least 25 Watts.

Yes, many years ago, before my IT career, I could produce 150 Watts for an extended period. I was unusually fit for a few years, about the time of ALGOL-68.
Then I got a desk-job.

My right knee feels like gravel. I have other desk-job ailments. My output on the cycle machine was not even 17 Watts at first. I was very depressed. After several weeks, I did make 25 Watts in bursts (so the machine display ran on me-power for a couple of minutes).
