I was fortunate after a very good career to retire at 58. I have been offered consultancy work ,but I love my freedom which retirement brings. What is priceless is that you have time to enjoy living without the shadow of having to go to work again. Mid week games are great knowing you can chill the next day. Being retired can mean a drop in income ,but being a time millionaire makes up for it.Speaking as someone who is now coming into my mid 60s and retired just before I was 60 my advice would be to do it (retire) if you can. I had a good career and enjoyed most of my working life but gave never looked back since I finished work
Your 60s may be your last good decade, if your lucky you will also be healthy into your 70s.
Some of us live too long, others not long enough.
We downsized, paid off the mortgage, sorted the kids out with deposits, bought a little place in Spain and I started to play golf.
TBH if I only got another five years before I croak I wouldn't feel cheated.
