I'm handicapped.  I had AFOs as a kid (those things cause blisters like no other).  I hate walking, I hate hiking.  But by damned if I made it a distance on a hike, I was going tot make it back come hell or high water -- without any help.  No matter how exhausted I was, or at the end of the pack.  Christ these lard buckets are mental weaklings to give up so easy.
