Go for it. Best thing I ever did for my sanity was retire. A combination of things, partially dumb luck, means I'm actually putting $ in the bank every month.
I've always lived within my means - raised by parents who went through the Depression & WW2 - and outside of my cars, have few expenses.
I generally manage to stay pretty busy, still catching up on things I wanted to get done years ago.
Mainly though, the less BS in your life, the better - and healthier - you'll be.
The BS and propaganda on TV included.
