Episode Highlights & Timestamps
00:00 — Welcome & framing: “Where science meets soul.” Aging as a cellular story you can influence.
00:47 — Mini-science moment: Telomeres 101 — stress shortens; movement, meditation, nutrient-dense diets protect. “Self-care is cell care.”
01:23 — Origin story: Why Mary-Beth wrote the book after years of colleagues asking, “What’s your secret?”
03:10 — Simple > shiny: How explaining the why (e.g., hydration for cognition) beats “quick-fix” serums.
04:04 — Posture matters: Hunching ages your look and affects breathing, reflux, pelvic floor; small tech nudges help.
06:03 — Top non-negotiables:
Hydration for joints, skin plumpness, hunger regulation.
Sleep for hormone balance, detox, appetite control, mood, and skin.
Movement with strength training for muscle, balance, and bone health.

13:07 — Time to self-care when you have zero time: The graceful “no,” micro-habits, and boundary scripts.
21:06 — Sustainable fitness: Track steps, lift light but often, leg weights during chores, stair rules, park far.
23:39 — Micro-workouts: 8-minute routines with countdowns; “see the timer, finish the set.”
28:32 — Step science: Why steps compound; turning scrolling and phone calls into step breaks.

31:59 — Starter kit: Facial brush, daily SPF, greens powder, sleep mask, light dumbbells/ankle weights, guided meditation.
37:29 — Reframing aging: “Don’t let the old man in.” Mix with younger folks, pick a passion, avoid health-obsession talk.
41:30 — Gentle behavior change: Wean, don’t white-knuckle. Swap sugary soda, celebrate small wins.
44:26 — Outro & resources.
Mary-Beth’s Core Playbook
Hydrate early & often: Aim to sip throughout the day; dehydration = brain fog, snack cravings, dull skin.
Protect sleep like a toddler: Consistent wind-down, dark room (sleep mask helps), same wake time.
Lift something most days: 8–15 minutes counts. Prioritize legs and hips for balance and bone density.
Move incidentally: Park farther, stairs up 1 flight/down 2, walking phone calls, dance while cooking.
Posture cues: Wear a gentle reminder device or set hourly “shoulders-back, ribs-down, long-neck” check-ins.
Mindset alchemy: Reframe stress, practice tiny gratitude reps, and assume good intent.
Boundaries without guilt: “I can’t do X, but I can do Y.” Trade four-hour dinners for a coffee walk.
Quick Wins to Try This Week
Water before 3pm slump: One full glass before reaching for caffeine or sugar.
8-minute lift: Two dumbbell moves + two bodyweight moves; set a timer and go.
Sun-smart skin: Daily moisturizer or foundation with SPF on face, neck, hands—365 days/year.
Walk-the-errand rule: If it’s within a mile, feet > car.
Bedtime guardrail: Screens off 45 minutes before sleep; use a sleep mask.
