When I arrive at the institute, I learn that Castellani is ramping up a new project to test soldiers’ manual dexterity in cold temperatures. Long before hypothermia or frostbite sets in, a person experiences a slowdown in fine motor skills. This slowdown is one of the first signs that a person is getting cold. Loss of manual dexterity might mean that a soldier in the Arctic who is trying to change a flat tire might not be able to thread lug nuts onto the bolts. And when a vehicle is out of commission, the supply chain isn’t moving as efficiently as it should.
