Enlisting in the Military

Why do people enlist in the U.S. military? It’s genetic:

Analysis of twin pairs drawn from the National Longitudinal Study of Adolescent to Adult Health (Add Health) revealed that 82% of the variance was the result of genetic factors, 18% of the variance was the result of nonshared environmental factors, and none of the variance was accounted for by shared environmental factors.

    A. It is a family tradition.

    B. Get away from mama and do something on your own for the first time.

    Don’t twin studies account for stuff like family tradition?
