Sharma then began biking to retirement homes to visit veterans in his hometown.
He records the interviews on video and burns them to DVDs, which he gives to the veterans, CNN reported. He also has begun posting the interviews to his YouTube channel.
In 2016, Sharma founded Heroes of the Second World War, a nonprofit organization dedicated to preserving interviews with WWII combat veterans for future generations. He also set up a GoFundMe account to pay his expenses. CNN reported. So far,he has raised more than $182,000, which helps pay for his travel expenses and video equipment.
His age prevents Sharma from renting cars or checking into many motels.
"I live out of the car when I'm on the road," he told CNN. "(It) makes my job a lot harder."
Sharma realizes he cannot interview every surviving veteran, so he doesn’t mind a little help. He told CNN that anyone who is interested in his work can contact WWII vets in their communities and record their stories.
"We don't need to use iPhones to take selfies," Sharma said. "We can actually document history with them."
