If You Can't Hear This Sound It's Probably Because You're Old

Do you remember back in school when some clever bastards managed to get hold of a sound that only young people could hear? So everyone would be going out of their minds because of this irritating high-pitched squeal - but the teacher didn't understand what was going on?

Some may say that it was the perfect crime.

Well, it turns out that there's a whole host of different noises that only people under a certain age can hear.

How weird.

As I'm 25, I must say my heart broke a bit when I couldn't hear the last two noises on this video. I'm officially old.

Here, try it yourself...

I'll just be in the corner crying over my lost youth.
