In thinking about Wolverine, Conor MacLeod (the Highlander), Aragorn (LOTR), etc, I was wondering how they would might live undetected in today's society. I mean, if you reached a certain age and you weren't aging, somebody's going to notice. You'd have to fake your death and drop off the radar. But what then? Live on the streets as an unnoticed homeless person? Change your identity every now and again?
