Pretty sure I'm considered "elderly", but any stranger knockin' on my door is likely to find that to be the other way around. Nothin' more dangerous than an old man who is armed to the teeth, and pissed off!
Some of us need to take classes in Cane-FU .I think it was on Youtube about classes for ANYONE of any age that needed a devise to steady their walk. Youngest was about 5-6, oldest 90 or so. They taught them how to use their device to do one heck of a job on an attacker.
What fun, first thing they taught that the old ladies really got into was to go for the BALLS, The man that was suited up in head to toe protection got whacked about most sharply, fell down and was given a good work out.
