In the 70’s, I remember the scoliosis checks. They would show pictures of people with horribly misshapen spines, diagnosed as scoliosis, then make all of us girls (boys separately) take our shirts off and bend at the waste to be examined by the “expert”. Some got the dreaded diagnosis, for which there was no remedy. Humiliating. Upsetting.
They’ve since discovered that the ‘experts’ were sometimes pedophiles and the pictures they took were circulated amongst other pedos.
