You've no doubt heard the horror stories from people who've brought their smartphones with them to another country and were surprised with a roaming bill for thousands of dollars.

I have recurring dreams of it happening to me. When I travel overseas, I bring along a paperclip to remove my SIM card from my iPhone when I'm on the plane so that when I land in another country I don't get charged AT&T's exorbitant international roaming fees. Call me paranoid, but I have read reports that people get hit with roaming charges even after they turn the roaming setting "off" on their phones. By removing the SIM card (which is easy) I'm ensured that I won't get an unexpected fee.

On my last few trips abroad, I've purchased data SIM cards ahead of time. I've had great experiences with B-Mobile for Japan and HolidayPhone for Italy. I had a terribly frustrating experience with RebelFone (Here's my post about b-mobile and RebelFone).

1) Drink water instead of soda. And drink tap water, not bottled water. Soft drinks don't contribute much to your body beyond chemicals and empty calories, and there is growing evidence that both the sugary-sweet and sugar-free varieties are associated with a variety of elevated health risks. Water is essential to human life. Your body needs it. And why waste money on bottled water that sits around in questionable plastics, possibly transported from the other side of the world with a ginormous carbon footprint, when the stuff that comes out of your tap is safe and healthy? (People who live near fracking sites in the US, or in developing countries without potable tap water, I'm not talking to you.) Sink-mounted water filters or filtering pitchers are an economical option if you prefer filtered water, but come on, quit wasting your money on bottled water. It's dumb.
