In the tra­di­tion of Atul Gawande and Sher­win Nuland, Marc Agron­in­writes lumi­nous­ly and unfor­get­tably of life as he sees it as a doctor.His beat is a nurs­ing home in Mia­mi that some would dis­miss as ​“God’swaiting room.” Noth­ing in the young doctor’s med­ical train­ing had quitepre­pared him for what he was to dis­cov­er there. As Agronin first learned­from nine­ty-eight-year-old Esther and, lat­er, from count­less others,the true scales of aging aren’t one-sided — you can’t list the prob­lem­swith­out also tal­ly­ing the hopes and promis­es. Draw­ing on mov­ing per­son­al­ex­pe­ri­ences and in-depth inter­views with pio­neers in the field, Agron­in­con­jures a spell­bind­ing look at what aging means today — how our bod­iesand brains age, and the very way we under­stand aging.
