Interviewer: Welcome back. Up next, age and the generation gap. We know how hard it can be to tell someone's age, but in fact it turns out there may be a way chat's quite simple. It's called the 'Mosquito1'one Test', and Mark is here to tell us more.
Mark: Thanks, Sue. The Mosquito Tone is a sound —a very high pitched, very annoying sound, which is why it's named after the insect. What's interesting is that apparently as we age, we slowly lose our ability to hear this sound. According to scientists, almost everyone under the age of 25 can hear the Mosquito Tone, but almost no one over 25 can hear it!
Interviewer: Really! Is that right?
