Vida loved to keep fit. Whenever she could, she went to the gym after work. But one evening, Vida got home late. ‘It’s too late to go to the gym now,’ she said to herself. I'll just watch TV instead.’

She made herself a nice, fresh, healthy salad and sat down in front of the TV. Suddenly, she saw something on TV that caught her attention. It was an advert for an exercise bike called the Fitmaster 5000.

That looks fantastic!’ thought Vida. ‘I think I’ll buy that!’

She phoned the number and ordered the machine. It came the next day.

It was much bigger than it looked on TV, and the only place Vida could put it was at the top of the stairs. She loved the Fitmaster 5000 so much, though, that from that day on, she only exercised at home. She didn’t go to the gym any more. She spent hours every evening on her exercise bike, and every evening she went faster and faster One evening, she was going so fast that the exercise bike began to move forwards. Before she knew what had happened, she - and the bike - fell down the stairs. All sixteen of them. Right to the bottom. Ouch!

The Fitmaster 5000 was broken, and so was Vida’s leg.

‘I think that’s enough exercise for a while,’ thought Vida, as she lay in her hospital bed. ‘And that’s enough watching adverts on TV too.’
