If I get time today or tomorrow, I’ll have to see what the average is. Guessing around 40
I'll lower the curve, I have spent ZERO years married and I'm quite happy with it.
Never worked a full time job, comfortably retired the first time at 40 and found myself bored in 3 years and returned to working seasonal jobs for 20 years. Retired again 3 years ago, maybe it'll stick this time, maybe not.
