What better way to celebrate your 105th birthday than to ride a rollercoaster?

You'd be the oldest one out there.

OK, maybe not the oldest. Robert Weighton, the sassy king who turned down a card from the Queen, just turned 108. But still, you're kind of an ancient oak surrounded by bushes.

In his JustGiving page, Jack Reynolds said he decided to raise money to help fund the local air ambulance in Yorkshire.

"On the 6th of April 2017 I will turn 105 years old so I've decided instead of sitting back to read my second letter from the queen I'd rather raise a little more money for a well deserved charity and also see if I can gain my second Guinness World Record by attempting to be the oldest person to ride a roller coaster," he said.

I mean look at this picture. He's so relaxed. He gives zero f*cks.

This is a video of the endeavour, and again we can see Jack waving and enjoying the ride, just as he probably enjoyed the crazy ride of his life:
