I'm female, and I ran my first marathon at age 52. Now 58, and I just did a rim-to-river-to-rim one-day hike in the Grand Canyon. No health issues. Still haven't fallen apart.
Did that myself a few years ago and definitely one of the most memorable days of my life.
Currently not sure my ankle, damaged by years of cutting sports, could hold up to it.
But otherwise can't complain too much about health.
-back MRI (revealed problems with my fusion from 38 years ago but manageable)
-One ER visit (turned out was nothing)
-Nuclear stress test (flying colors)
-2nd ER visit
-Cath lab, stent #2 in the widow maker
-Dental stuff, broke crown
-Colonoscopy (flying colors)
For new year looking forward to:
-New ankle x-rays (heading toward possible ankle replacement)
-Consult with orthopedist for ankle and back
I am really a lot healthier than all that sounds
