  When I was at university we had to run on a treadmill and exercise bike whilst breathing through a mask. We measured how much oxygen and carbon dioxide we breathed and what happened to our heart rate when we exercised. It was fun to see the differences between people who exercise a lot compared to the couch potatoes!

  Some people might not like this, but as part of my degree I had to dissect human bodies (which really means cut them up!). It was so interesting to see inside an actual human body and I loved it. Not everyone did though….a few people fainted and were sick, so it is not for everyone!
