My best advice would be phased retirement. Obviously, some people just want an immediate change. But for me, I wish I had reduced my hours by one or two per week. Maybe retiring completely at 2 days per week.
Spending more time with friends and family is much more important to me than money. Between social and financial considerations, I value travelling locally by foot, bus, train, or taxi. Because driving has lost all pleasure for me.
A staggered retirement would be great! I think that this would also be perfect if combined with grandchildren, in the sense that they would be able to spend a lot of time with grandparents, giving some space to parents, but also setting up the scene for experienced knowledge transfer in the things that are important.
I believe that one of the reasons the world is the way it is now, is because a lot of knowledge is not transferred, as we live so isolated from each other, even within families. We used to all be in the one house.
