Yes, I think about this from time to time as well. After all, you are using another man's razor, not a new disposable plastic piece that only you will use before it goes to a landfill.

That being said, we probably tend to romanticize our visions of the former owners, with tales of chivalry, civility, courage and, dare I say, aristocracy. The truth is most likely more mundane; perhaps a coal miner who worked 15 hour days, 7 days a week to support his 8 children who all ran around him while he shaved because his dwelling was a single room.

Yes, perhaps some things are better left to the imagination....
