On November 1, daylight saving time ends in the United States. That means most of us will “fall back” to standard time for the following four months. But many states want to stop this twice-yearly clock change and instead stay on daylight saving time all year. One question is at the center of this proposed change: What would permanent daylight saving time do to our health? Clare interviews Dr. Katie Sharkey, professor at the Wake Forest University School of Medicine, to find out – digging into the data on time changes, the body clock, and how proposed changes to the time system could affect our well-being.

A podcast combo with KUOW's Seattle Eats to explain the data behind tipping, plus a side of advice.

How much should you tip?

When someone says “reading is dead,” is that really true? Reading for fun has taken a big hit, but what’s really going on here? Teo and guest co-host Katie Campbell look at the data on American reading habits to find the answer, and provide tips for aspiring book nerds to get more pages in. Katie Campbell is KUOW’s book club curator. She has read over 51 books this year so far, but who’s counting?

Correction, 9/8/2026: In this episode, we incorrectly state that adult American gamers spend roughly 90 minutes gaming daily. The correct average time per day for gamers is two hours.
