You know, something I've been thinking a lot about is how despite all of our scientific

0:10.6

breakthroughs, despite these mind-blowing medical advancements, we make every year, and some of

0:16.3

them are truly, truly remarkable, we still often struggle with the basics. We can cure previously incurable

0:24.2
