Retirement is a time many of us associate with quiet days spent relaxing, visiting family or finally pursuing hobbies we’ve put off for decades.

But according to the Huffington Post, a group of retirees is now volunteering their hard-earned time to build homes for the needy.

The group calls themselves “The Swingin’ Seniors” and is based in York, Penn. They have been building homes for 15 years.

“Seeing the looks on the families’ faces when we hand them the keys to their new home is the most fulfilling part of volunteering,” Jones told the Evening Sun.

The Swingin’ Seniors are currently building a home for Abby Sheely and her 13-year-old daughter, Mekayla, who is confined to a wheelchair. Mekayla has cerebral palsy.
