back to the future car
The manual wheelchair has been doing use for years and possesses been subject to many changes. The constant feature has been that this chair is self propelled by pushing on the hand edges that surround the wheels. The owner actually pushes the wheels around and around to get from one location to the other. In addition to that, the footrests with a manual wheelchair is easy to remove as well as the user can walk the chair forward with his feet. However the humans living around the spaceship were different to the humans who will be living in the world now. They were so fat them to be unable to walk. they travelled around in motorised chairs having a monitor and cup & straw attached, chatting on phones and when they happened to fall out they simply laid there until a robot arrived and picked them up. The adults were fat, the youngsters were fat! They just laid around all day long consuming doing no exercise what so ever and quote the captain, "Computer, define dancing".
