As Joyce reminded me in myinterview, I have known what it is like to walk, although it has been a long time (a matter of years) since I have been able to do it with any regularity.
In recent weeks, however, I have begun to experiment, standing again, using my crutches, for short times. In the last few days, I have been able to stand for longer and longer periods, sometimes as long as 10 minutes. I am still a long way from having the confidence to attempt to walk yet, but I am sure that this will develop with time.
Ironically, I am writing this while feeling dramatically weakened by a raging stomach bug, so I have not been able to stand up at all in the last two days, because I have felt too unsteady when I have attempted it.
Everything else seems stable. My breathing and my heart are still behaving themselves very well, so I am sure that I will regain my strength reasonably quickly, and that I will be able to get back on my feet very soon.
