This week, we talk with Jamie Tworkowski, the founder of the mental health-advocacy organization To Write Love on Her Arms, about the organization’s mission and the U.N.’s World Health Day (April 7), which this year is themed “Depression: Let’s Talk.”

Writer and podcaster “Science” Mike McHargue also joins us as a special co-host as we take listeners’ advice questions, discuss advancements in robot technology, ponder the intricacies of “sea law” and a lot more!
