Nearly everyone has many opportunities they have never taken because they choose not to. How many older people have never
- ridden a motorcycle
- gone fishing
- gone hiking
- knitted
- cooked a complex meal
- gone sailing
- been skydiving
- read a lengthy book series
- played in a local sports league
- coached children
- painted a house
- painted artwork
- sculpted anything
- built a simple things out of wood
- built a complicated thing out of wood
- welded
- taken a canoe/kayak/inner tube down a river
- gone white water rafting
- travel (all kinds!)
All of these things are accessible to the average physically fit person into their 60s. Even the ones that don't often have special access options for those with disabilities.
But people frequently choose not to try some things because they assume they won't like them or because of construction concerns, but they also overlook a lot of free or nearly free experiences that they could always try. I haven't even done all of the things in my example list!
