I'm not a big proponent of those events where they simulate disabilities for a half hour or whatever, for a number of reasons. But this YouTube video was kind of interesting.
It shows a group of able bodied friends using a wheelchair to race through a house to see who can go fastest and/or match the time of the wheelchair user. Every person had a different reaction - one guy didn't finish after falling down, for example, while another was determined to beat the time. Although it's important to keep in mind that the experience of using a wheelchair every day is much different than these one time attempts, I think the video is useful for remembering one thing: when people assume how hard it is to live with a disability, sometimes that assumption is based on the perception of a person new to the experience and equipment.
On the other hand, this video also shows how barriers in the environment are the main reason getting around is tough.
