Fatigue. Weight change you did not cause. Words that go missing mid-sentence, hair in the shower drain, a cycle that has gone strange.

Generic sun advice was not written for a body sitting a mile above sea level. At Lafayette's elevation, the same July afternoon delivers measurably more UV than it would at the coast — and skin already losing collagen to perimenopause has less margin for error.
