Got zapped by my Engine !

I'm at the end of the current P/M's life. They were showing what they were going to replace it with.
That thing isn't much bigger than a wrist watch. I'll be able to have an MRI as well. Not that I'm looking forward to an MRI, but it would have helped a few years back.
Really? I don't think I would ever trust that, no matter what they said. That sounds kinda risky.
