I'm about to reveal just how old I really am. Not with a number but a memory.
As we were helping Amy and Jared move into their new place, which is really a
VERY OLD place but new to them, I accidentally made a discovery that took me back to my early childhood. I opened the medicine cabinet in their bathroom and I saw one of these...

No, not the bottles of products to make you smell and look amazing... the little slot on the back wall of the cabinet. Anyone know what it is?
Well I do. I'm THAT old... Sigh.
I remember seeing those when I was a kid on the back of all medicine cabinets. It is the graveyard for old razor blades. I'm not sure many of you will even remember when you just bought the blades for a metal razor. For most of your lives you've probably only seen the plastic razors that you just toss when they get dull. Allow me to educate you on some old school shaving trivia. Back in the day we had razors that looked like this...
You would twist the end of the handle and it would open the two sides of the razor where you could remove your old dull blade and put in a new one. Some ingenious person that had probably more than once sliced their hand open on an old blade while emptying the garbage can decided to invent a great way to dispose of your used blades. You guessed it... you drop them in the slot at the back of your medicine cabinet where they fall into the recesses of your wall never to be seen again. That is unless you or some future owner of your home decides to do a little remodeling and tear out the wall. Then this is what awaits you or them...

So... before you tear out any old bathroom walls be sure you've had your tetanus booster shots.
Who knows what having this information might do for you? It may make you a million dollar winner on a game show someday if not at least you can astound your friends with your knowledge the next time you stumble across one of these bathroom treasures.
