So? if those stop you then still need to learn a lot.

I doubt it.

In the situations I often have to work in that probably wouldn't even
see the end of the day. Well, at least not alive. I've even had a wrist
watch crock on me.

I had several wrist watches crock,
this happened specifically when carrying big TVs through narrow doors.
But you would be surprised how strong that is.
You can even break the PCB and it will keep working.
I have dropped stuff like that too, without any problem.
Some worked for 25 years, and then was till OK, but replaced by more modern stuff.
What I like about this system is that I can prototype in a few hours,
and have it working, while others are still waiting for the peeseebee to
arrive, and then often have to do version a, b, c before it is OK.
And also making changes, if it is a one of, is much faster.

That sounds like a strict-liability lawsuit waiting to happen :-(
