1. Ever wonder why you don't usually hear your own footsteps? Why you're not surprised by the sound of your keyboard while typing? Or how you can (sometimes) ignore the sound of your keys jangling in your pocket?

Probably not. But @janani_ss and I did! 2. Why, you might ask? Well, because recognizing (and ignoring) the sounds you make -- while seemingly superficial -- is a key component in how we learn and maintain more complex behaviors, like speech or music.
