I think you're having a hard time understanding what I am saying. You state "Someone with his age and experience shouldn't have made such basic mistakes." Well he was mentally impaired at the time. That is why he did make those basic mistakes that you refer to.My point wasn't that he got lost because he was old. Just the opposite, that someone with his age and experience shouldn't have made such basic mistakes, thus why I commented it is such an odd situation. I think you are looking for offense where none is meant.
