WHY is my voice still high?

Bugzy, you really have a thing about your voice breaking, don't you? At 13.5 years old you're well on the way. Your voice will either crack suddenly or slowly slip down the scale. Nobody can say which way it will go but either way you'll know it. As you already have two recordings, why don't you make a few more. It's so easy nowadays and it might give you some interesting research as well as being a nice record to remember your childhood. I don't know if any other kids have done this sort of research so you could be a first. I reckon it's well worth doing.
