I can proudly say that last year I broke the record for the oldest person in the world to ride a roller-coaster. I'm 105, but I feel younger. Even the doctor agrees I'm in good condition. I'm a bit deaf and my legs feel weak, but they are the only issue.

I rode the Twistosaurus at Flamingo Land, which spins you round quite fast. I didn't choose to go on that. I'd have preferred a really fast one that went upside down. But I was told I couldn't ride something like that, because my blood pressure could drop and I might have some danger.

I wasn't nervous - I don't get frightened of anything. I was securely fastened, so I knew I wouldn't fall out. The roller-coaster ride went on for three or four minutes, and it couldn't be a better experience. And I raised a lot of money for the Derbyshire, Leicestershire & Rutland Air Ambulance fund, which was fantastic.

People were saying I'd got a place in the Guinness World Records. Later, someone came to present me with the certificate. I had it on the wall in my living room, with another one that got a year earlier.

My record-breaking ways really began a couple of years ago, with the ice-bucket challenge. It turned out that I was probably the oldest person in the world to do it, and the video was very popular. After that, I stared to think about what else I could do to raise money for different charities.

I'm not sure if anyone admires all the fun I'm having. They just say I'm daft and that's about it. But I've had many good days and many exciting times. I've had a really good life. I don't think I've wasted any of it.

24. Why didn't the author choose to go on riding the Twistosaurus?

A. Because he was in a bad physical condition.
