People in their 40s and 50s with no children, how does it feel?

I wanted kids when I was younger, but wasn't ready to give up my freedom. Once I was ready for kids the world (and the future in particular) looks so bleak that it doesn't seem fair to the theoretical kiddo to say 'hey, here's a dumpster fire - good luck'. Instead I babysit for my friends and family, spoil the kids around me, and sleep in on the weekend. I also have more time for activism and trying to ensure a brighter future for kiddos.

No regrets.
