Mr. Boxy
The larynx, the organ that produces our voice, ages just like the rest of our bodies. The muscles around the vocal cords atrophy, making it difficult for us to control how it directs air. The superficial lamina propria, which form the outer edge of the vocal cords, stiffen and become thinner, reducing the vibrations that create our voices.


Normal vocal cords are straight, and readily vibrate when speaking. In the video, you can see that the edges of the vocal cords barely move unless he really tries to be loud. He also has a slight gap near the top of the cords. This lets air flow through no matter how he speaks, giving his voice a reedy sound.
