Great insights, Roughkype. Introducing individual characteristics like skin and beard type, ergonomics and skill level (duh!). I'm recalling Malcolm Gladwell's book "Outliers," in which I belive he states that on average, for someone to master a task they need to do 10,000 repititions. At one shave per day that's 30 years! Well...with 60 years of shaving for a male, that means everyone who starts young enough can get there. Barbers get there faster of course. And I'm sure many of you have natural talent for it. Anyway, at 65 and little, if any, natural talent I'm not gonna make it to master class but I'm having fun on the journey. Look forward to more to ponder.
