That's a tough one for me. I've had congenital hearing loss since I was born-very bad in my left ear, moderate in my right ear. So I've had to rely on my sight to help compensate for that occasionally. Yet I can't imagine not hearing my children, or my wife, or my kids.
Yet my eyes have taken a few beatings in the last few years. My old dog, who just died last summer, and I were playing about 8 or 9 years ago, and he inadverdently scratched me right across the center of my left eye. The vision in that eye, that was almost perfect, is no very bad uncorrected. Then about 2 weeks ago, I was tussling with my 3 year old son, and somehow I accidentally poked myself in my right eye. For about a week, driving at home at night was a nightmare, as everything was very distorted. It got better over the week, and I also started to wear my glasses driving home, so it's given me a new appreciation of my eyesight as well.
So I can't decide!
Btw, I just went out today and ordered a pair of hearing aids from Miracle Ear. Had the molds made today, in fact. They're having a sale-buy a pair of their regular hearing aids, and they upgrade you to their top-of-the-line digital hearing aids-it's about 3 grand for the regular pair, and it normall costs over 6 grand for the top-of-the-line digitals. I should have them in 3 to 4 weeks, and I'll let you know how it's helping me.
