John Green went to Ethiopia to learn about an amazing woman by the name of Dr. Mulualem Gessesse. She’s a modern-day MacGyver (of string and tape fame), using tubes and water and hacks to make sure her outdated equipment can help babies in need. She has set the standard for neonatal care in the developing world and has helped cut the infant mortality rate in half in Ethiopia. Which is kind of stunning. Hear her story and learn how you are connected to it. At 1:58, the thing she figured out is simple and brilliant and should be happening everywhere.
