This is the text (if you need help).
People who walk slowly at the age of 45 may get old more quickly. They could get physically and mentally older. Doctors know that older people who walk slowly are more likely to have health problems. Slow walkers in their 70s and 80s often die sooner than fast walkers. This may be the same for people in their 40s.
Researchers looked at the health records of 904 people. The researchers looked at the people's memory and intelligence. They did tests on the people. The people had to say the alphabet while walking. The people who walked more slowly showed less brain activity while saying the alphabet.
Back to the walking speed lesson.
