Our heart rate never changes - it stays in the range of 70-72 beats a minute until you
reach 85 years old.
The heart doesn't beat faster - it actually slows down to save energy for your muscles.
Our heart rate increases when we exercise so that more oxygen and nutrients can be
transported to every cell in our body.
