So how old are you?

Apparently there are these ringtones that adults can't here. I can here up to 17,000Hz but no higher. Once you're at the website, select Mosquito Tones, then select it again and then again. You should now see a list starting with 14,000Hz ending with 20,000Hz. Start off with 14,000Hz (just select and hit preview). You should hear some high pitch, really annoying ringing. Goodness gracious, I'm deaf. My ears are still ringing after that. Oh and if your curious, here's the story.
