An interesting video about vocal cords, it involves the filming of inside the body so if you don’t like that sort of thing don’t watch!

Sometimes I worry my hearing will go for various reasons, mostly all those scare stories about headphones and such like. I came across this today on Neatorama which omitts a high pitch sound usually only heard by Under 25′s and I could hear it…which I should being 23, but it was still most fun! Give it a go yourself.
