Linda, that is unusual, the way your legs collapse if somebody happens to brush up against you. Could it be an exaggerated "startle" reaction?
I jump out of my skin at every sudden loud noise. As far as I can figure out, it's an exaggerated startle response, probably because of spasticity.
I have problems with people coming up behind me in a store (or anywhere, for that matter). I'm not aware that they're there, I take a backwards step, and suddenly I've stepped on somebody!
I have hearing aids but they aren't much help when it comes to being aware of what's going on behind me.

I don't want to get in trouble for going off topic in this thread, and so I'll mention that I found the "Golden Years" forum and am glad to see it here.
I have mixed feelings about it. In a way it looks like a form of segregation, sort of like admitting that no younger person could possibly be interested in what "oldsters" have to say, and therefore why not put us off in a corner by ourselves.
On the other hand, maybe what we have to say is so choice that not everyone is entitled to know our pearls of wisdom. Make them work for it! Make them seek out the Golden Years forum and check out our posts!
(I'm mostly joking. I should probably keep my mouth shut since I'm so new here.
