Quite how the regulations are dealt with I don’t know, but starting work as a Japanese farmer appears to require one to be at the very least a septuagenarian, although ideally it would seem they’d still prefer someone a little more senior.
And yet despite their advanced years, these ageing agriculturalists have the mindboggling ability to bend down for periods of time so prolonged that afterwards someone more than half their age would seriously struggle to stand up — let alone straighten up.
