The human body obviously has its limits. You just can’t out run a grizzly bear. Your car can. You can't see the edge of the cliff if you are far sided. You with glasses means you can. Your heart can now last as far as your pacemaker will. Your eyepiece will allow you to access the Internet from anywhere, and thus, you can have near infinite memory. Each ensuing advance in technology leads to the next fantastical frontier of assistive robotics.

Now, for someone that is five thousand years old, one of the next most pressing medical issues that he must face is atrophy of the mind. No cane, nor any modern mechanical device could really solve a condition as serious as Alzheimer's. The capacities of medicine in this matter are vague. Zed's five thousand year old mind is visibly and without a doubt suffering form the classic symptoms of Alzheimer's: dementia, memory loss, decline in thinking skills, personality and behavioral problems, such as agitation, anxiety, and delusions.  Of course Alzheimer's affects far more people around the world than simply Zed here. In fact, 45 million people worldwide have Alzheimer's. 

So the question here is how can robotics help?
