I hear you! Well, I hear all those people that told us we should buy a one-story house, etc. Then I watched the netflix series on the Blue Zones, and the main advantage of the one in Italy seems to be that the elderly continue to walk up and down super-steep roads, daily! They live longer than those in nearby Italian towns! They are less likely to fall, I guess, because they're used to doing that kind of walking... stronger cores and all.
