Dancing is better than just going to the gym - which tends to use only one set of muscles at a time. Dance uses every part of your body, it’s aerobic, uses spatial awareness, helps with balance, is good for flexibility and uses your brain, because you have to remember your steps.

I eat sensibly and exercise all the time, so it’s a complete puzzle. It’s linked to all sorts of diseases, so a bit of a wake-up call. Now I take a spoonful of Inulin every day, a supplement that was suggested to me.

If you can get fit enough to do this, you can add years to your life. Stand barefoot, cross one leg in front of the other and lower yourself to sit cross-legged on the ground without using any other part of your body. Stand up the same way.
