My friend Tamara has some unique skills. She can identify airplanes that are soaring overhead, telling me exactly what kind of planes they are. But maybe more interesting than that, she can take down a man twice her size. You see, Tamara was trained as a member of the IDF, the Israel Defense Forces. At age 18, service for their country is mandatory for Israeli citizens. We call this conscription, meaning that the government gets a hold of you for a very specific purpose.
