Calibrate
A Precision Medicine Approach to Women's Hormones, Cognition, and Peak Performance in Midlife
Midlife is treated as a decline to be managed. It is, more accurately, a physiological change that can be measured, understood, and worked with.
Calibrate sets out the evidence in order: what changes, what it does to cognition and performance, what the data can tell you about your own physiology, and what to do with that information.
Publication date to be announced.
EVIDENCE
What the literature supports.
MEASUREMENT
What your own data shows.
PHYSIOLOGY
What is actually changing.

The argument, in order.
If you've been meaning to get to the bottom of why the last few years have felt the way they have, start here.

Evidence. Perspective. A Plan.
Rachel Smith, DNP, is a doctorally prepared nurse practitioner in women's precision medicine and the founder of Aspect Wellness.
Her clinical work is longitudinal and measurement led: comprehensive assessment, careful interpretation, and a plan reviewed against real data over time. Calibrate is that method, written out.
