Hey everyone! I was feeling a little under the weather today and decided that I was going to read you an excerpt from a medical physiology book. To go along with the theme of me being sick, I focused on the chapter all about immunity. I hope you were able to learn something as well as be relaxed, get tingles, and be sleepy. My goal is to either help you learn or to remind you of being in school during lectures and bore you to sleep.
To listen while using other apps, switch the player to Picture-in-Picture (PiP) during playback — it keeps playing in a small floating window (the screen stays on).
