Book a standing shift, not a favour

A job, or a team you ran, gave you somewhere to be and people who expected you. Retirement takes both on the same day. Helping out when someone asks doesn't replace that.

Older people who volunteer die less often over the following years. Pooled across studies, the gap was about half. Once researchers adjusted for other differences between volunteers and everyone else, it was about a quarter. Evidence: decent In a US study of about thirteen thousand people over fifty, the link showed at a hundred hours a year or more, roughly two a week. Evidence: decent

Now the honest part. All of this is observational. Healthier people volunteer more, and adjusting never fully removes that; look how much the gap shrank when they tried. So I won't tell you it adds years. Nobody has shown that. Evidence: decent

The "standing, not a favour" part, and the first month, are my reading, not a test: a fixed slot gives the week back its shape. Evidence: worth trying

If the weeks after the role ended have brought low mood, or you've lost interest in almost everything, start with a doctor, not a rota.
