Hahahaha. Awesome. I'd never heard of that, but based upon observations of the same elsewhere I'd lend it credence. I certainly didn't see loads of super old people in Japan on my (month long) trip, even in places they might traditionally be found (high ranking Buddhist monasteries) but perhaps that was just the places I was hanging out (rural north of Kansai, Kansai).

Or making robots act as Japanese seniors. The sky is the limit.
