He's celebrated his last three birthdays by smashing Guinness World Records.
Jack Reynolds is no ordinary pensioner. The 106 year old from the UK is officially the oldest person to get a tattoo and the oldest person to ride a roller coaster.
Now, he's gone and completed his third Guinness World Record - by riding a 60 metre high, 400 metre long zip wire.
Jack broke the new record live on Good Morning Britain and it looked like he had mighty craic.
The daredevil from Derbyshire didn't do it just for the laugh.
No, he completed the task to raise money for the Stroke Association.
What a legend!
