I concur. The VA says there's nothing wrong with me, but they should try and tackle stairs when the arthritis and bursitis are acting up.
And while the "typical" concealed carry permit holder may not be wheelchair bound or have similar disabilities, what do you tell them?
OTOH, in one of my earliest blog posts (The Clue Meter: But will it replace shuffleboard?) I linked to a Wall Street Journal article entitled Everybody Is 'Cane Fu' Fighting At Senior Centers, So Watch Out - WSJ. (Old enough that it's out from behind the pay wall. There were videos, to, but I lost track of them.)
Apparently, some Senior Centers are teaching escrima. Which might work for some seniors and others with disabilities.
One thing I worry about is that talk of what training someone with a carry permit "should" get will lead to an impression that "If they don't, they shouldn't carry." (Note: NOT saying anyone here believes or suggested that.)
Myself, I think Eddie Eagle should be required in elementary schools, and Home Firearm Safety in Junior High, but after that, anything else should be "encouraged" but optional.
(Private ranges should be tax-exempt, to encourage safe firearms handling!)
