Legs, armpits, beards, "other" places... Most adults in modern Western society shave something on our bodies to remove unwanted hair. And according to Wikipedia, we've been shaving in some way, shape, or form for a long time-- since the Bronze Age.
In 1895, the concept of the safety razor was conceived by King C. Gillette and the arduous (or artful) task of shaving was revolutionized. Then came along Schick, Bic, and then the electric shavers all to add to the list of modern conveniences. And, well, you know the rest. Or do you? What about all of those single-use plastic disposable razors that we use once or twice, then pitch into the garbage and landfills to remain in perpetuity?
