This is a preamble to a novel of the world of pain my hands, arms and joints were in afterward, at my age and shape. And yet despite being an overpaid typist like most of us here, I regularly do heavy repairwork and maintenance, such as digging 110' drainage ditches on my property by hand, shovel and mattock.
