PLEASE don't retreat away discouraged! I definitely find the topic of interest, even tho my first reaction was, "Crikey! I wish they'd just invent a perfect hearing aid in the interim!" I think part of my own jaded response is utter frustration to keep having this stem cell carrot dangled in front of my nose. At one point stem cell research was declared ILLEGAL I think, despite the good that can come of it. Give us another chance, cuz it's better to know what's out there and keep that kernel of hope alive.
I can related to the issue personally as that is exactly the problem I was born with: BALD as an egg in my ears. It's a hereditary condition in my family. But I confess, I actually daydream about injecting my ears with Minoxidil to see if that could stimulate some hairy growth. I think I hammered my last 10 ear hairs attending an Elton John concert back in the '70s - with NO ear protection. DUMB.
