There's Plastic In Our Bodies. Now What?

What if the plastic container you're heating your leftover lunch in is actively rewriting your hormones?

Environmental chemist Dr Paul Harvey unpacks the terrifying reality of microplastics, explaining how these tiny particles act like "micro knives," physically scratching our delicate gut lining and leaching creepy, hormone-disrupting chemicals into our system. Food scientist Dr Emma Beckett also weighs in, offering a much-needed reality check on balancing plastic panic with actual food safety.

Then, we dive into "matressence," the massive, identity-shifting transition into motherhood. It turns out "baby brain" isn't a myth or a social media trend; real neuroimaging shows a mother's brain structurally prunes its grey matter to specialise for a baby, right as estrogen and progesterone drop off a perimenopause-level cliff.
