A Nebraska rancher who once guarded Nazi war criminals is in the record books nearly 80 years later, reports the Guardian.

A 100-year-old Nebraska WWII veteran became the oldest organ donor in US history after donating his liver through Live On Nebraska in Omaha.

Several Hollywood legends and political figures have lived past 100. U.S. Census data shows the number of Americans living older than 100 is increasing. The oldest person on record lived to be 122.

The veteran's son credits his father’s longevity in part to a lifestyle rooted in physical labor and homegrown food.
