> back breaking outdoor labor that has a high likelihood of causing musculoskeletal healthcare problems by one’s 50s, Are you sure about this, I mean non-anecdotally? Much might depend on the type/repetitiveness of the labour, etc,etc, but in general I suspect most HN-fiddlers are (mutatis mutandis)in poorer physical shape than labourers. There's little more dangerous to a mammalian frame, designed for a life of outdoor physical activity, than hours of inactivity. The sofa and car are probably the two most physically dangerous items we've come up with. I started to notice most of my peers having become functionally disabled by car and sofa abuse by about their late 20s.
