2 nights, 10 years ago when I was 52, broke my leg bad on an elk hunt, hypothermia was the most concern the first night, had surgery the next day to repair the leg.
Doc said I would never work construction again and to bring paperwork for SSI, I hobbled out and my wife said, he doesn't know you... was on the job site 3 months later hobbling around and was 75% after the first year.
