My wife is in the hospital right now. People are taking precautions, but she's well attended to. In fact, it seems like someone is checking on her every ten minutes, or at least that's how it seems every time I visit or talk to her on the phone. And they all have such high energy levels. I couldn't imagine doing that kind of work. They're very social... well, most of them, anyway. Some maybe seemed like introverts, and they also didn't seem to be content in the high energy environment.
I'll tell you one thing, though... Nurses earn every penny they're paid. They seem to be running around, tending to people's problems from the moment they get to work until the time they leave. And they can't make mistakes. People's lives depend on their competence.
That's something I liked about writing software. If I had a bad day and my work wasn't up to par on that day, I could fix it the next day. And before it was put into use, it was tested. You can't do that when you're dealing with critical factors in real time.
