The scientifically false pretense that vaccines are perfect will be maintained as long as dialog is suppressed. With my own hands I administer vaccinations, but I have a responsibility to ask my own questions while supporting parents in their right (and responsibility) to make carefully considered decisions for their children.
The ancients knew that children of a certain age pass through a change that is profound. In their metamorphic transition from childhood to adulthood, they become different beings.
For a long, long time now we have known that the change increases their need for sleep and shifts their biological clocks. The consequence is that they tend to fall asleep late and then wake up much later. Despite the presumptions of some early-rising adults, it isn’t laziness.
