Gurven is also co-director of the Tsimane Health insurance and Life History Project, a collaboration between UCSB and the University of New Mexico.

I have no idea the quantity. Dozens, many, many people all taking turns. And so, after about 4,500 chest compressions – – and almost one hour in the cooling fit – – Joe Tiralosi’s doctors brought him back again: chilly, fragile, but alive.
