I had to ride in a wheelchair once and it was not fun!
Awh that is unfortunate,  I hope you are okay now though.  Wheelchairs date back a while, back to 525 CE in Chinese art. 
Yeah I'm all good, it was temporary. And man, I never would've thought it would be in China first.
Yea China made a lot of advancements in early history.  It was considered the dominant culture in East Asia.
