I have a relative who works with "public health" in NY City government clinics. Have heard many stories about people too lazy to take prescriptions, or kids with ailments and zero adult supervision to help cure them.
Unwillingness to take meds is a long-time problem with psychiatric patients. It’s hard to imagine not taking meds when you are dying of a physical ailment.
I knew a girl once, a hippy girl (age about 19), back in the 70s, who went on a carrot juice diet. She only drank carrot juice. Nothing else. She became extremely listless, extremely skinny and she turned bright orange. Her mother dragged her to a doctor and the doctor told her that if she didn’t start eating food she was going to die. She came to her senses, resumed a normal diet and went on to become a (fairly) normal adult.
Lots of pregnancies due to laziness.
