Now we have epidemics of duck-face selfies, gender dysphoria, aggressive illogic, social media addiction, delusions of self-importance, reading incomprehension, compulsive lying, inoculations of poison, and gratuitous masking.
Gender dysphoria is a great example. The number of girls wanting to be boys is up 2500% in the last 10 years. Boys wanting to be girls is up 100%.
Back in the 1400’s(?) there was a hysteria where people believed they were made of glass! One of the Kings (France?) at the time had to be packed in straw and a wooden crate to be carried to the bathroom! The hysteria lasted for 100 years or so.
