Is Your Voice Changing as You Get Older?

As we get older, our voices lengthen. Our vocal cords are wearing out naturally. I like to think that i'm trying to go back to my baby state of allowing in the voice to function as it was designed to do. My pet peeve a subway system: We are higher intellectuals than animals. But i feel that trying to get on a subway, we lose all base of humanity. And i seeing old women be run over by guys just trying to make the subway and the next train is only two minutes away? That's my big pipe.
