The hidden health benefits of wearables technology with Michael Snyder
Michael Snyder is a professor and genomicist who wears eight pieces of wearable technology every day: four smartwatches, two rings, and two hearing aids. These devices give him a personal data dashboard to help him understand his health in real time. In this interview, Michael joins Sherrell to discuss how wearables can help you identify health conditions, from irregular heartbeats to a COVID-19 exposure, to even which food triggers your glucose spike. The two also talk about why everyone should wear a CGM (continuous glucose monitor), how wearing wearables can help you stay more accountable to your health goals, and why it’s important to know who owns your data.

The past and future of clean transportation with Doreen Orishaba, Daniel Sperling, and Gil Tal
Electric vehicles have a surprisingly long history. Battery-powered cars have existed since 1881. So why did the world choose to spend over a century investing in fossil fuels? Sherrell explores this question with a talk from engineer Doreen Orishaba. Doreen built Africa's first electric vehicle and now runs 100+ electric buses across East Africa. Her success proves that the countries that did not inherit a broken infrastructure may be best positioned to build what comes next. Then digs deeper into the background of electric cars in a TED-ED lesson from Daniel Sperling and Gil Tal.
