I agree with you about the machines and different folks running them.
I absolutely can't 'work' my husbands cel-phone... I've decided it hates me...lol
My husband has a bit of a struggle getting my desktop pc to work correctly and we've yet to figure out why...

I can't wear a watch because they die quickly. I gave up trying to wear watches years ago. I wonder if I could wear one now? It's a sad fact that our bodies change with mid-age and I could have lost that extra elctro-magno-don't know, what it's called that killed watches...

I'm going to ponder some more on that...
