In case you haven’t seen this: Chicago police released bodycam video of officers rescuing a man who had fallen into ice-cold Lake Michigan. They formed a human chain to get him out.
The guy had been walking his dog when it fell into the water . . . and then HE fell in when he rescued it. But then he couldn’t pull himself out. According to a report, his body temperature got down to 93 degrees, which is close to hypothermia.
