All concluding year, and now I listen to my ipod everyday. I also play guitar relatively often. I don't infer I keep none of these idea to loud, sometimes the ipod, but never ever have the ipod on full blast, nor my guitar amp. I can hear okay out my left ear, and my right ear only just feels adjectives stopped up and can't here like my moved out eye. I can feel I her more on my departed ear than right. I wonder how did that occur, because when I be younger, I had impeccable hearing. I'm studying Japanese, and I wanna be a pilot. Japanese to me I can get, but they talk so speedily, I want to be able to comprehend. As far as me being a pilot, I want to know if I can still catch a class 1 medical certificate?
