I'm simply curious about what the OP considers "Old Folks."
I surely don't know. I'm 74, and I won't say how old my wife is, but she isn't allowed to contribute to her IRA anymore.
However, I consider myself one of those "reasonable fit adult males" someone was talking about. While my wife, who is also "reasonable fit," struggles with arthritis in her right thumb joint, which makes it difficult for her to operate the slide on
some pistols.
Note: I didn't say my wife
can't operate the slide on some pistols, I said it's "difficult" for her to operate the slide on some pistols. She loves her Sig P239, and she's real good with it even though it's harder for her to operate its slide than it is for her to operate the slide on her Smith EZ .380. Besides that, her Sig P239 is bigger than her Smith EZ, making it more "difficult" for her to conceal on her 5'2" (only 5'1" now that she's older) 120lb frame. Again - "difficult," not impossible.
On a side note, a couple of weeks ago, my wife and I both realized how much we've "aged" in the last few years. I killed a good-sized mule deer buck right at sunset on opening day, and even though I was able to back the truck right up to the dead deer, my wife and I had one heck of a time getting him loaded. And it was well after dark before we got him home - which is only 12 or 13 miles from where I shot him. Then we were another hour getting the dead deer hung up in the shed.
Just a few years ago, we would have said that was a "really easy hunt." This year we were stiff and sore for 3 days afterwards, and last night was the first night in 2 weeks that my wife was finally able to sleep on her right side again.
