Science (Biology): How old are your ears?

How old are your ears?  What a weird question!!  Why would the age of your ears even matter?  Did you know that as you get older you can't hear higher pitches in frequency?  Did you know that there are actual cell phone ring tones that are at these higher frequencies so that your students can hear themselves getting a text or all, but because you are over 20 you probably can't hear the tone.  In this video by AsapScience on Youtube, you will actually get a chance to see how old your ears are.  This video does an excellent job explaining the science behind it as well as actually demonstrating this scientific concept to your students and yourself.  See how old your ears are.
