Then it's wonderful for soldiers... I'm not tryin' to be a soldier right now.
Maybe a wrist-worn metrenome?
Well, when someone on any stage looks at their watch (which they'll inevitably do), it makes them look like they want to get out of there (politician often make that mistake, and it looks bad).
Now that I'm retired...
My appliances have timers that beep so I know when the food/whatever is ready...
I usually remember that Tuesday is trash night...
Band rehearsal is here, so I'm already here when they arrive...
My wife's voice is in earshot of my mancave, so she'll let me know if something needs addressed.
Occasionally I leave my home (favorite place in the word), I prefer not to drive in the dark,
and I seem to manage aaaall that without a watch on my wrist, or even my phone at the ready.
