We DON'T Have To Think About Every Step We Take...Thankfully!
I took my family to the Houston Museum of Health & Medical Science where they had an exhibit called Star Wars: Where Science Meets Imagination. They had one interactive display of a pair of robotic legs and you could contol the hip and knee of each limb. The goal was to get it to walk from one side of the platform to the other. Sounds easy? While watching, most weren't able to do it. Then came my 10 year old son Ariel, a major Star Wars fan, who had a go at it. This was his second attempt:
OK...he made it look easy.
In reality, having to control each joint individually leads to a disjointed and, well, robotic gait. And he didn't even have to worry about he ankle or anything about the foot! We're so fortunate that our brains are able to process at the speed and efficiency which it does in order to integrate all of our body functions. This simple experience made me grateful and helped me understand, in a very small way, the effort that victims of stroke and other brain injuries have to go through to rehabilitate.
