Dec 4, 2025

Summary

Host Alex Goldman investigates why listener Heath suffers from severe, persistent armpit stains despite rigorous cleaning. With help from microbiologist Dr. Chris Calivart and NBA laundry expert Joe Cuomo, they discover the stains are caused by stress-induced apocrine sweat rather than just aluminum antiperspirant. The episode concludes with advice to wash clothes immediately after emotional events and avoid dryers to prevent setting the oily stains.
