[Gentle music plays, we see an older man in sunglasses driving in a convertible car, then walking into a swimming pool. We hear a man speaking.]

"I'm Bill. Well, I happen to be 90 years old. I'm a fitness instructor, specialising in aqua aerobic exercise, and I've done that for the last 20 years.

It was my retirement job. After I retired, I looked for something to do."

[The man speaking is now shown sitting down and looking off screen to an unseen interviewer. He is identified by text on the screen as "Bill, Fitness instructor, Ashburton Pool and Recreation Centre". He continues speaking while we see shots of him setting up his equipment by the pool for his class, and then leading the class and later talking and laughing with people in the class.]

"The first few days, I saw all the tradies going to work in the morning, in their utes, and I had nowhere to go. So it gave me a new focus on life to be able to do something like that.

Once you're retired, once you've finished your working life, your life hasn't finished, has it?

You've probably got a good 35 year ahead. People are going to live longer, and it's important not only to live longer, but to live a healthy life after that. And the only way to stay healthy is by being physically active, mentally active, not give up.

Well, when I first started, I had about four or five classes a week, but then fame spreads, and I used to do up to 20 or 30 classes some weeks.

My family, Peg and my kids say, you know, Dad, you're getting a bit old. You should slow down, take it easy. But take it easy, what for?

My objective always was to keep fit. And the water is a great environment.

I do what we call the active adult classes. People in the hydro pool come after injuries, they might have had a knee replacement or hip replacement, or people come with their walking frames, and they leave them on the side of the pool, and then they're in the pool, and then they jump around like mad.

Simply get out of the house, join something, do something. Even if it's volunteering here or there, or for men, join a men's shed, or any of those things, to get among people.

When you get old, it's very easy to become introverted. And once you're in an environment where you do exercise and have fun with other people, you can forget about your aches and pains. Lots of people have them, but it's not so important, you can get out of that.

There's nothing special about me. I'm just doing what I'm doing, and I'm going to keep on doing it for the next 10 years.

I look forward to the celebration when I'm 100, and I'm still here.
