Life Skills, Episode 2: Move. A 7-minute plain-language lesson. Movement works like a dimmer, not an on-off switch: the first step up from very little carries most of the benefit. Paluch 2022 (15 cohorts, 47,471 adults): vs ~3,553 steps/day, hazard ratios 0.60 / 0.55 / 0.47 at ~5,801 / 7,842 / 10,901; the first ~2,200 extra steps carry a 0.40 drop. Inactivity ~9% of premature deaths (Lee 2012, modelled). Exercise for depression (Noetel 2024, 218 RCTs): walking/jogging 0.62, yoga 0.55, strength 0.49, low confidence. Strength training 30-60 min/week ~10-20% lower mortality (Momma 2022). Programs add only ~500 steps/day (Conn 2011). Do this week: 3-day step baseline, 'If I finish lunch, then I walk 15 minutes', two 20-minute strength sessions.
