Somewhere between deadlines, screens, and constant stimulation, reading became less about productivity and more about permission. Permission to slow down. To sit with a thought longer than a caption. To let language stretch. This year, I’m returning to books not as an escape — but as a grounding practice. I used to think reading needed
With Just Two Flagship Products, This Startup Is Quietly Building the Most Revolutionary Hormone Health Platform Since Bioidenticals Were Invented. For years, the women’s health category has remained frustratingly stagnant—full of outdated hormone therapies, generic skincare routines, and a medical system that often treats women’s symptoms as disconnected, “normal,” or too complicated to address.
