RSVP paired Hager with Habitat for Humanity in New York’s Steuben County, where he does everything from test light fixtures to sort screws. He has volunteered more hours than anyone else in the organization for a second year in a row.

Oh, and he’s 100 years old.

Born on May 17, 1917, Hager has spent the last century giving back to the community.

"Harold has been with us for a few years years now, and he's the volunteer who does the most number of hours here," Matthew Harmer, the marketing and outreach coordinator for Steuben County's Habitat for Humanity, told WENY News. "He works the equivalent of about a 20-hour work week."

Hager joined RSVP after his wife died in 2010. The two wed in 1939, and were together for 71 years and one month, almost to the hour.

At an RSVP event in May, Hager was recognized for his hard work and dedication. He declared his next goal is to reach the age of 105, but no matter what, he said he plans to live out the rest of his life giving back to those around him.
