Eureka! Bob Mcdonough looks like most folks his age. Greying hair, a soft smile, but unfortunately can't remember much. He suffers from dementia. 

Mr. Mcdonough wandered off into the Maine woods and was missing fro over 14 hours. This pompted a search and rescue mission, and it ended up with a very happy ending. As you can see from the above video, Mcdonough wandered right up to a news team that was covering the story. Amazing.
