Technology is advancing at warp speed, and the way we live is changing constantly. Indeed, what was once lifestyle bedrock is now going the way of the dinosaurs.
For example, when I backpacked in Europe more than three decades ago, I kept in touch with my family by way of aerogrammes and postcards. Those days are gone. My daughter just started her study abroad program in Copenhagen, and within hours of hitting Danish soil, I heard from her by way of Facebook messages and mobile telephone calls via Skype.
