It strikes me as an odd story to be sure. Bizarre even. If I took a spill and couldn't remember my name I think I'd probably head to a hospital or seek out the authorities. Had he done so the whole issue would have been resolved in minutes or hours. Of course, he probably wasn't in his right mind if he forgot his name.

Also odd that a farmer would offer/accept an offer of work from a older gentleman that couldn't provide his name. It was good of him to help but a phone call to authorities probably would have revealed that there was a search for him, again ending the saga quickly.
