Jack Reynolds is just enjoying the ride that is his life.

On Thursday, the great-grandfather from Chesterfield, England, marked his 105th birthday by becoming the oldest person to ride a non-inversion roller coaster.

He whizzed around the Twistosaurus’ track at the Flamingo Land theme park in Malton to set a new Guinness World Record.

“I was amazed. I was really amazed,” Reynolds said after the stunt, for which he raised more than $450 for his local air ambulance service with the help of his grandson Shane Spencer.

The retiree told ITV’s morning program “Good Morning Britain,” which broadcast his ride live, that he’d only expected to “just go round and round” as he’d previously done on a wooden coaster in the 1930s.

But, he said cheerfully, “every bit were good.”

He's done it! Well done Jack for new @GWR live on @GMB today. He was doing it 4 us. You can support him here https://t.co/ape3Sy5ELE pic.twitter.com/H0o6CbkHG9 — WN & DLR Air Amb (@WNDLRAirAmb) April 6, 2017

Reynolds is no stranger to breaking world records, and on being presented with his latest accolade, he joked that he’d have to move out of his bungalow to better accommodate all of his awards.
