This woman has a great attitude, and the right attitude.
She may not be a champion, but she loves her sport and she knows that if you want to be doing this at this age, you just mustn't stop doing it. If you stop, you may never start again.
So whatever sport you love to do, the way to be able to keep doing it is, firstly, don't stop doing it. Secondly, we think you should make sure you train enough so that the parts of your body that aren't worked by the particular sport are as strong as the parts that are.
