I think you will find that things get even better with the arrival of grandchildren. Mine are now in their 20's and I wouldn't trade an hour that I spent with them for anything. A lot of what I thought I would do after I retired, has no interest to me now.At a period of life when things should be slowing down to allow more time for my hobbies, I find my time being consumed everyone else’s. I expect that will only get worse now that grandchildren are in the picture.
