I had a minor surgery in the surgical department today, and my mind was racing with all sorts of thoughts

I'm not afraid of hospitals
and I'm good with needles,
but maybe it's because I'm getting older,
but all sorts of thoughts kept crossing my mind.
From things like, "I guess I'll have to undergo a major surgery at least once as I age..." to "What if something goes wrong during the surgery?" and so on...
Health is everything.
