I and my wife enjoyed many miles of travel in 28 years and six MH's, retired at 54 to add to travels and last long trip was in 2010 because wife was going on dialysis that year.
Because of added health problems with wife can only have weekend trips now, but my age of 80 in Dec, and site problems will put a damper on driving the MH.
So the health issue will determine what most of us fear.
I have always said enjoy your travels as much as you can because the end can come unexpectedly.
I almost had my end at seventy but had a
angel of a doctor that got me this far.
Enjoy and be safe in your travels everyone.
