I thought of you as I was writing. Health issues are something you can't argue with. Many musicians have been forced to retire for medical issues, some normal and some self inflicted. I was going for the mental aspect of the job. I still really enjoy making people happy even if I have to play those same songs for the 1000 time.
I'm glad to hear your going to enjoy yourself and keep doing whatever gigs you feel like
Good sailing.
