Welcome back !
I'm 66 and have been retired for 2 years...it's wonderful...everyone should try it
Since I retired and have been able to resume my preferred riding schedule...working 5 day 12 hour swing shifts really really sucked...I've lost 27 pounds and am at a weight I've not seen since my senior cat 3 days. Not quite the same fitness lol but working on it.
I love being able to ride when I want, how long I want with no worries about anything but chores around the house and relaxing...it's wonderful.
Good luck and enjoy your life...we only get one and too many of us just seem to piss it away...trying not to be on of them.
