Now do this put-the-text-back-together activity.
This is the text (if you need help).
Cycling keeps us healthy. It is good for our heart and mental health. Surprisingly, it is also good for our knees. A study says older cyclists have less knee pain. Researchers asked 2,600 people about their physical activity. They also took X-rays of the people's knees. The X-rays showed signs of knee problems.
A researcher was surprised by the research. She said cyclists were 21 per cent less likely to have knee problems. When we use our knees a lot, the joints wear out and become painful. Knee problems usually start when people are in their fifties. Cycling is a great way to stop us having problems with our knees.
Back to the cycling and knees lesson.
