In my day, I said in my best fatherly baritone, men all over the world began each morning by shedding their own blood. Shaving almost always meant cutting yourself. Guys sometimes came to work with bits of toilet paper stuck to their faces. There were styptic pencils.
All that's changed. Electric razors appear to be just as useless as they always were, but the improvement in razors and blades is astounding. I can go weeks without the slightest nick, and those pivot-headed multi-blade systems (so easy to mock in theory) are actually completely wonderful.
There is probably ample fodder here for a disquisition on evolving technologies, social customs, the difficulties of making hedonic adjustments in the measure of inflation etc. I leave that to others; i just want to focus for a minute on how much better the world is in so many ways that we hardly even think about.
