I purchase a bag or two of disposable razors a year for $12 each. I use each razor for at least two weeks then snap the cover on the blade, pitch it and grab another. When I shave it's deliberate and hurried. I don't cut myself, I don't miss a thing, there is no burn and it's over in around 60 seconds or so. So just because someone chooses a more modern and streamlined approach I don't think it's fair to say they never "learnt" to shave. And really, I must offer an of my own.
