Once again, this group proves to be a valuable source of information. Sometimes, even well intentioned MDs are not a good source. There's a big difference between treating a disease and living it. I appreciate everyone's feedback and I will keep an eye out for some sort of well balanced stick and see how it works... if for nothing else than to poke my son who left the laundry basket in the path. Now when he was a toddler, I had padding swathed around all those sharp furniture corners lest he fall against one. Perhaps I should consider PD proofing my house.
