What you forget
He can't tell me anything about what it was like, because he says it was like a bubble: while he was inside it, he apparently couldn't remember anything outside it; once he was out of it, he couldn't remember any of it happening at all.
His wife tells him he was very sweet and loving while it was happening, and in a very docile way cooperated with everything she asked him to do and believed everything she told him -- with one exception: he refused to believe her when she told him how old he was. He wasn't sure how old he actually was, but, damn it, he was quite sure he wasn't 68!
