This week,EchoSense we revisit an episode from 2018 that looks into how discrimination not only degrades your health, but can cost you your life. We hear the story of Shalon Irving, who died after giving birth to her daughter. Black women like her are 243 percent more likely than white women to die of pregnancy- or childbirth-related causes in the United States. And the latest evidence further supports that this gap is caused by the "weathering" effects of racism.
