Meet the Author

Hi, I'm Taryn Eagle.

I wrote What to Expect After 40 because I couldn't find the book I actually needed. Not a clinical manual. Not a doom-and-gloom warning. Something honest, funny, and real — that treated aging like the wild, weird, surprisingly empowering thing it actually is.

I'm a retired U.S. Marine and retired Police Officer. I'm an ISSA Master Nutritionist, Fitness Coordinator, and Transformation Specialist with an MBA. And I'm also just a struggling human who hit 40 and thought — why is nobody talking about this stuff?

"Aging isn't about losing your youth. It's about finding your power."

— from What to Expect After 40

The book is equal parts comedy and comfort. The Solutions Guide is the practical follow-through — the specific peptides, supplements, workout protocols, and biohacking tools our experts personally use every day. Not theoretical. Not cherry-picked from studies. What they actually do.

Individual results will vary. The Solutions Guide shares personal protocols and is intended for informational purposes only — not as medical advice. Please consult your healthcare provider before starting any new supplement or protocol.

The Writing

Honest. Hilarious. Actually helpful.

What to Expect After 40 isn't a medical textbook or a self-help lecture. It's the book your best friend would write if she happened to know everything about what's happening to your body — and wasn't afraid to say it out loud.

Taryn's writing style is warm, direct, and genuinely funny. She doesn't sugarcoat the weird parts of getting older — she leans into them, finds the humor, and then gives you something useful to do about it.

The Solutions Guide is the natural next step — the practical companion that takes everything the book covers and turns it into the specific, actionable protocols our experts use personally. Not a generic plan. Their actual stack.
