For some reason I was thinking about Spinal Tap, at the end, when the guy says he would sell hats if he wasn't a musician.
So if you weren't a nurse, what would you have become?
If I was being serious, probably a social worker, because when I went back to school, I was debating between social work and nursing.
If I was being whimsical, I'd be an astronaut. Even though I think I'm too tall, and know I'm too out of shape and don't have the science and engineering brain for it. But it's a fun thought!
