Thirst Is a Lagging Indicator
Dr. Debbie Chen found the water signal in her own PhD data around 2007, laughed it off, and did nothing with it for a decade. Then came years of amateur Muay Thai and cramping through every session, then a dehydration health scare of her own. She’s now founder and CEO of Hydrostasis, maker of the GECA Watch, which has sold out twice. She and Neal get into why thirst is a lagging indicator, why she believes hydration is the only truly actionable thing a wrist device can measure, the multi-pivot road from collegiate sports to older adults, and the data-equity problem she won’t stop talking about. Plus El Patron in Mira Mesa - a first-time mention on the show.
