In my travels this is the most frequently asked question. MEA stands for Middle East and Africa. In fact it covers more than that as we also have parts of Europe (Cyprus, Malta, Turkey), Pakistan, Tahiti (Yes Tahiti!), and more.
But what about a more simplistic answer? Well I usually just tell people "85 countries, give or take depending on current border disputes". It's not only a disarming answer, but its truthful. MEA is a dynamic region and while noone wants wars, border disputes and the like, they are a fact. But we tend to focus on the positive and although we even have countries like Iraq, Afghanistan, Iran, and many others, I refer to our region as "dynamic" instead of the usual word of "troubled" that many use.
