Most travelers know to shower before they fly. It's common sense that when you're going to be captive for hours, with no personal space, the last thing anyone needs is body odor. What some new travelers don't realize is that even the tiniest amount of aftershave or perfume can be toxic to cooped-up fliers.

At home, your loved one may adore the smell of your fu-fu, but people sitting near you on a packed flight, will not -- and there is just no way they can get away from it.

So, to recap: shower; wear fresh, clean clothes; but please hold the cologne.

You're returning home after living overseas. Perhaps you've been gone only a few months... or perhaps you've lived in a foreign culture for a number of years. It's possible that you became fully immersed into that host country and culture. Now, you're facing repatriation back to your home culture.

Sometimes, people experience what is known as Reverse Culture Shock when returning to their original homeland: it's a surprising mixture of bewilderment, loss, isolation and confusion. Your home country may no longer feel like home, and you may not feel like you belong there. Preparing for successful "re-entry" often depends upon applying skills of adaptability, change, and flexibility to ease transition back into one's home culture.

Recognize that you are a different, new person.
You've probably changed significantly by living overseas. Viewing our old home from an international perspective may reveal new -- sometimes scary -- insights into our home culture, other societies, and ourselves. Your new attitudes, cultural sensitivities, global awareness, and broader viewpoints may or may not be in sync with the folks' ideas back home.

Maybe you're not even sure where home is anymore, or maybe you feel more connected to your host country. It's ok to feel confused. Another name for this feeling is "personal growth," and this is just a growing pain.

Remember that your home country has changed, too.
Changes -- big and small -- happened while you were away. If you were back for home leave or a short visit, you may have already observed some changes. But even tiny alterations in fashions, products, advertising, customer service approaches, bank fees, and political attitudes may combine to create an entirely new, strange environment.
