I live in germany but I tried to use common sense. In this scenario our society would be split into two groups if we pay pensions for eternity: Those who lived long enough to receive their pension. Their body turns 30 again thanks to breakthroughs in science. And those who never age beyond 30 and so they never get their pension. The first group effectively gets "basic income" and they probably own houses/apartments so their living costs are quite low. You can either let everyone have pensions or get rid of pensions.
