Heat Debt
A cooling mat rated for six hours never lasts six. A pillowcase from the freezer holds its cold for forty-five seconds against skin. A woman stands in her kitchen at 3 AM, damp from a shower she's learned to calibrate precisely — not cold, never cold — and cannot remember what she came in here for. Her phone tracks a number in amber and red that climbs from May and never fully resets before the next May starts it climbing again. She is functioning. The bed where her husband was is dry and cool.

Normal Range
A seven-year-old squeezes a dynamometer in a Houston clinic. Eighteenth percentile. Within normal range. Three years ago, the reference curves were redrawn to accommodate what a committee called contemporary activity patterns. The new curves run lower. They have to. You can't flag sixty percent of your patients.
A pediatrician moves through her Tuesday. She checks grip strength, listens to lungs, orders vitamin D on children in the sunniest city in Texas. Everything she measures falls within range. The range is current. Whether current means the same thing as correct is what her hands keep finding.
