If you fancy a challenge try creating a mind map with the opposite hand. Unless you are ambidextrous this is quite a test for mind, eye and hand co-ordination!
You can alternate which hand you start with.
The test is a great indication of how brilliant ours brains are, how we learn and how we perfect skills.
No need to stop at drawing; try other tasks such as stirring your drink or brushing your teeth.
Try discovering the most complex task that you can undertake using your opposite hand to the one you would normally use.
