Depends on the definition being used. Most of us are getting up there in age a bit, if for no other reason than long range hunting & shooting tend to be expensive ways of using firearms and folks don't tend to burn a lot of optional money on already expensive hobbies till we're older and more financially stable. Getting old goes hand in hand with starting to show signs of wear. All of my non-functional parts are limited to sensory organs so I don't think it's nearly the same as for those with actually missing or non-functional body parts. Nonetheless, good challenges are there to be had and taking them on is, for many folks of our general ilk (I'm assuming here), part of the spice that makes life tasty.
