Soldato
I went to three days a week when I was 51, don't regret it at all. 56 now and will probably call it a day when I hit 60.Have to say this strikes a chord with me.
I'm planning to go part time or maybe 3 day week in my early 50s and get the hell out of servitude ASAP. I have way too many interests to be bored in a lifetime of retirement. Assuming I live that long, there's no guarantees with life
