1Japan's towns are growing older, and one coastal community has responded with an unusual experiment in volunteering.
2Retired residents earn credits by helping elderly neighbours with shopping, hospital visits and minor household repairs.
3Those credits can later be exchanged for similar help when the volunteers themselves eventually need support.
4The scheme, which began informally among friends, is now coordinated by the local council and a small charity.
5Organisers say the system works because it treats older people as contributors rather than passive receivers of care.
6A former teacher, aged seventy-eight, spends three mornings a week driving neighbours to their medical appointments.
7She jokes that the scheme gives her a reason to keep her driving licence and her diary organised.
8Loneliness, which doctors increasingly describe as a public health issue, has measurably declined since the programme began.
9Similar time-banking schemes are now appearing in Europe, adapted to fit different welfare systems and local customs.
10The deeper lesson is that an ageing society can remain generous, provided its institutions make generosity easy to practise.
