Who Has a Right to Your Body?

We hardly exercise self control, and mostly react to clues in the environment.   Self is a set of behaviors we have adapted, otherwise self is barely controlled.

In the linked article they ask, what right does a child have to their body?  The answer is very few, their environment is severely restricted by the behavior of others and culture. We deliberately limit the choices of childfren by restricting other adults and using symbols in culture.
