I don't know about you, but every morning I shave. It's a ritual -- shower, comb hair, shave, brush teeth, dress.

Showering is easy to understand. If you don't shower, you start to stink. Combing the hair is easy to understand too, because it would be a mess if you didn't comb it. If you don't brush your teeth, they rot and fall out. And dressing, obviously, is a necessity.


But why is it that, for a majority of men, all facial hair must be removed? There certainly isn't any health reason to shave it off. Why would we spend the time and money to go through this ritual each and every day?

And what about the technology of shaving? A number of companies in the United States and around the world make billions of dollars off of the simple act of shaving. These companies release new products constantly. Is all of this technology really necessary?
