There is a common expression, and one I've used personally, that refers to the non-sensical issue of losing an item. It goes something like, "if my head wasn't attached I'd lose that too". Losing anything is frustrating as well as time consuming.
All too often we're in a hurry to get somewhere, or even finish a project. I'm a good one for leaving my tools in odd spots when I'm working in the outbuildings. Since my memory is so vague I spend more time retracing my steps trying to find where I left something than actually getting anything done. Now, if I also had to deal with keeping track of my various body parts along the way, I don't think I'd ever find myself in one piece again.
I can imagine looking for the tape measure and finding one of my ears hidden under a newspaper. Or looking for the hammer and realizing, "oh, that's where I left my toe!". It's one thing finding my coffee cup on a fence post, but to find a butt cheek flopped over the clothesline is another thing.
I've even misplaced a shoe before, but to find the foot I've been missing along with the shoe would really make me question my sanity. Although, much to my relief, I have looked in an old jacket only to find an item I thought was lost for good. But to find where I left my nose would feel like winning a jackpot.
And what about finding lost items on the road? Many of us drive cars so it would be much easier to find our missing body parts in our vehicles. But what about those of us who ride motorcycles? Heaven forbid if we're ever behind a motorcyclist who doesn't have their head on right.
I know I've lost my mind before but at the present time I'm 93% sure it's where I left it. But, naturally, that's not saying I won't lose it in the future along with a few other things. Makes me think that's why fanny packs were invented. Why else would they be used?
