This is an interesting interview with the author of the new book, "Shock of Gray", Ted C. Fishman. A journalist, Fishman has put together predictions for how global aging will impact the world. One interesting point: while the article begins with the issue of global aging as a problem, Fishman doesn't necessarily respond to the interviewer's questions in that way. Rather, Fishman highlights the potential opportunities created by the aging world population, and attitudes toward aging. I'm definitely going to pick this one up.
