I know a (former) nurse who recognized her own brain aneurysm symptoms, saved her own life by being able to react quickly and get to help in time. Knowledge is power, I guess.

Absolutely this, and for me, finally beginning to live the life I couldn't in my twenties. I was so busy alternating between scrambling and zoning out, I hardly ever did anything for myself that was really memorable. I was stuck in a loop, work and exhaustion, rarely making time for anything else. Now I have a supportive partner, a greater priority on deliberately making memories, and just enough extra money to not feel guilty trying a new restaurant every week or two.

I have gotten so much more out of the last two years than I did in the five years before that, because I'm deliberately choosing to do things like go for a lil Saturday morning walk instead of scrolling endlessly in a duvet. In my twenties I didn't even realize how much time I was letting slip away.
