This wild card assumes that nano-enabled self-diagnosis and self-treatment becomes pervasive. This would allow the general public to diagnose, monitor and treat illness themselves having their own ‘Doc in a Box’. Doctors may become redundant and the ageing population could increase. Although this occurrence is considered ‘wild’, it is very interesting as there are a number of ongoing research projects based around this technology, which if exploited could trigger this wild card. This would have a huge impact on people’s lives, drastically changing the way that we diagnose and treat illness and disease.
