He hasn't spoken any English in public appearances, so I assume he's bad enough at it that he'd consider it unhelpful or embarrassing. And yeah, it's been almost 40 years, he has a demanding job, and that job gives him constant access to translators. I wouldn't keep up with a language in that environment either.
thought he lived with a guest family for years in Iowa or something?
(seriously though i'd imagine he would lose quite a bit of what he picked up since he was in his 30s(?) then)
