Dear Ageless Traveler, Are you like me? I want to stay connected with new friends I meet while traveling… yet I rarely do. Lately, I have been doing a better job of maintaining relationships by using the latest apps to keep connected at no or low cost. Frankly, it took me a while to get used to WhatsApp, the popular international phone and text system. But now that I use it, I do keep in touch more frequently and have cemented many new friendships. Also, it's how families stay connected...
