XPRIZE’s $1 million face mask contest, and the link between urban design and immunity

XPRIZE is offering $1 million to designers of a protective face mask that people will actually want to wear. Also, many buildings and neighborhoods are designed in a way that help cause chronic health conditions like type 2 diabetes and heart disease. Dr. Richard Jackson, pediatrician and city design consultant, talks about why well-lit staircases, green roofs, bike lanes, and pleasant sidewalks matter, especially in the time of coronavirus.
