What’s it like? It’s like when your laptop is making a weird noise, and so you open it up to take a look, and you poke around, and everything seems okay. Maybe you blow some dust out of there, spin the fan with your fingers. And then you start putting it back together, and you think you’re doing a pretty good job, and you’re trying to make sure no static charges get in there and mess things up. And you’re all done except maybe a screw is missing, but that’s probably okay.
But then you try to turn it back on, and it just won’t start, and you plug it in a different way, and you shake it a little bit, but still there’s nothing. And you get angry, and you think about taking it apart again to try and properly fix things but you know you’ll mess it up even more. The whole laptop is ruined.
My job is a bit like that, except instead of a laptop it’s a human body.
