I immediately had a gut feeling this was likely to be one of those "ah ha!" moments, due to the following reasons:

• visual stimuli are massively important for People with Parkinson's;
• the shrinking of handwriting is a classical symptom of Parkinson's onset and we need to constantly challenge all such symptoms to keep the disease at bay;
• relaxation and escaping ingrained stress response is absolutely key to improving symptoms of Parkinson's;
• continually trying something new and challenging our brains to create new neural pathways is key to pushing the disease back and back.
