Y'know, Lewk, when I was 18 I had what you would apparently consider "elective" surgery. My upper and lower jaws were widened, at the recommendation of my doctors, by ~.8-1.2 centimeters as a so-far successful attempt to treat my sleep apnea which they predicted would end up causing a fatal heart attack before I turned fifty without treatment. It apparently doesn't matter that maxillofacial alteration is an acknowledged and recommended treatment for a number of medical problems (and my problem, in particular, is one whose incidence significantly increases with age), since it can be and is also done for cosmetic reasons then anyone over the age or 65 (or, y'know, any youth with a disability) should not receive any insurance coverage for it from the US government.
