That's interesting stuff, teejai. It's good to know, but my own personal feeling about this is:

So what!

It means nothing to me when I am (we are) still in so much pain.

It's like reading about all the so-called breakthroughs that are being made in cancer research, yet the standard treatments of chemo, radiation and surgery are still the only options available.

Sorry if I am not so enthused at this information, as I know it was provided to offer hope.

Unfortunately, I have none.
