Once we had followed our men all the way into their 80s, we wanted to look back at them at midlife and to see if we could predict who was going to grow into a happy, healthy octogenarian and who wasn't.
Depois de termos acompanhado os nossos homens até aos 80 anos, quisemos voltar a observar a sua meia idade e ver se poderíamos ter previsto quem iria chegar a octogenário feliz, saudável e quem não iria.
