Well, it looks like I'm in the minority here, but I say Biggest Loser, baby! I would LOVE to go on that show. What an opportunity to change your life! Traveling is awesome, no doubt, but you come back to the life you left....
But having said that, what about the possibility of having your calls routed to your cell phone when you're gone and IF they call, hop on a plane!?
Two great options, if you ask me....good luck!
