Right, I think you would need to check stats on how many people dropped out over the years due to health issues leaving behind these super healthy old guys to get an accurate picture.
Someone can be a part time office worker, part time tradesman.
This part-time aspect was one of the appealing aspects of ride-sharing apps when they first appeared. People with cars could have 9-5 jobs and before and after the job, exactly during rush hour, give a lift to a few people. Of course, they turned into the new taxi but controled by multinational corps and almost impossible to hail without a smartphone.
We are speedruning Tolkien's law of decay.
Health is the opportunity cost otherwise, but it's hard to price health. And I don't mean that it's priceless; the price is ambiguous - is my health worth less or more than what half my salary buys me?
For software engineers, this is a difficult question to answer. If I were working an entry-level job, my health would be more valuable to me. If I were at the peak of professional development (a figurehead at a massive company or someone whose work changes the world), my work would be more important. SWE work makes a lot of money, but somewhere in the range of where I value my health.
How much $ a year is your health worth to you? Not a rhetorical question, would be interesting to see some answers if anyone can come up with a figure.
Please don't take that as "Citation needed!" but rather genuine interest.
