Getting up stairs if you are disabled.
If you or a relative suffer from arthritis or pain in joints which makes climbing stairs difficult or impossible, try going up BACKWARDS! Although this sounds irrational, most people with impaired mobility can go down stairs and, meeting an obstruction, can go back up a step with little difficulty. Now extend this principle to doing the whole flight in the same way. The difference this has made to Heather's ability to get around is amazing!
