re: Seeking advice from the 60+ OT crowd

My advice for your 50’s is to keep living life. I didn’t really have any significant lifestyle changes. Our kids got older, so they became more independent and started going to college. We did more traveling and went more places on family vacations. It was fun.
From a professional standpoint, I think you hit your peak in your 50’s. You have more experience, confidence and “wisdom.” Take advantage of it. And stay in shape. It makes a difference.
