@john6206 the question you ask is a very personal one that really only you can answer. What do you wish to do with the time you have left? We all have that question to answer for ourselves. What priorities do you have surrounding your life? Spouse, children, grandchildren, more? Where does sailing fit into your own needs for happiness? Only you can answer those questions. For each of us, there will come a day when we no longer sail. That time may come for many reasons. It is perfectly fine for you to decide sailing is no longer something you need to do. Accept it. But base that decision on what you truly want.
Most of us here are on the side of continuing to sail as it fills our needs for happiness. Many will share their stories of continuing to sail, but I'm pretty sure there are those that have decided it is no longer what they wish, but you likely won't hear that side much. Believe me, it exists. You need to decide for yourself and what you want most. If you are at peace with that decision, it is the right one.
