All About You With Dr Shauna Watts Aging in Midlife: Longevity Expert Reveals What Really Drives It And What You Can Do About It
What if aging isn’t random, but predictable, measurable, and modifiable?
Longevity medicine isn’t about living forever. It’s about protecting your strength, cognition, metabolic health, and independence, especially in midlife.
In this episode with Catherine Johnson MD, Longevity & Precision Health Expert, we unpack what longevity medicine actually means for women over 40 and why the real drivers of aging aren’t what most people think.
This conversation is about understanding how metabolic health, hormones, muscle mass, sleep, and stress quietly shape your health span, the years you live well, not just long.
You’ll learn:
The difference between lifespan and health span
Why midlife is a critical window for prevention
How insulin resistance and cortisol influence weight gain and fatigue
Why muscle is an organ of longevity, not just something aesthetic
How stress shortens telomeres and accelerates aging
Why “normal lab results” don’t always mean optimal health
What actually moves the needle for long-term vitality
Many women in their 40s and 50s say, “I just don’t feel like myself anymore.”They’re not dramatically unwell.
They’re not in crisis. But something feels off.
This conversation explains why.
If you care about staying strong, sharp, and capable after 40, this episode will change how you think about aging.
