I don’t understand, are you confused at the age range for Boomers? It literally says it in the image…

I get where they’re coming from.

The starting point is normally defined at the time you came out of your mother’s womb, but it really shouldn’t be.

It should be started at the point where you first enter society as a child, and start learning your generation’s societal values.

Basically, when you started kindergarten, or Elementary School.
