Bloomberg:  Money might not buy love, but it can buy better health. And, to live as long as possible, the world’s wealthy are willing to pay up. Over the past few decades, the average person’s lifespan has risen almost everywhere in the world. In China, the U.S. and most of Eastern Europe, the average life expectancy at birth has reached the late 70s, according to the Organization for Economic Cooperation and Development, or OECD. People in Western Europe and Japan, meanwhile, can expect to live into their early 80s. Most rich people, however, are counting on living even longer—a lot longer, as in two decades more than average. In a new UBS Financial Services survey, 53 percent of wealthy investors said they expected to live to 100.
