When you walk with a pronounced limp, joints pop loud enough to be heard across a room with every step you take people have a way of over looking you, they know where you are from sound, don't pay attention to what/where you're looking, hell. I'd have a hard time sneaking up on a deaf person! It also gives you an excuse to be moving slower than those around you enabling you to be more observant.I think that ppl age out of one role and into another. In my case I have aged out of a fighter role and am now a movement casualty. My current role is in support. I collect gear and tools,. When eyes are needed and information gathered, I am one of many. The great part about getting old is that ppl discount you, so you become more socially invisible, and that has value. The more infirm looking, the more observant, like children, everywhere yet unnoticed. Thats another minuteman role. The eyes and ears of the local effort. I collect gear and tools. I network. I pass on training from younger days. There are many sides to this. Its an effort, not a lone wolf.
