Here's an astonishing fact: the crime rate among Japan's elderly is on the rise. And among an rapidly aging population with long life expectancy, that's a problem.

The island nation is famed for its nagaiki (長生き, longevity) with, as of 2013, a life expectancy of 86.61 years for women and 80.21 years for men. The oldest gen'eki (現役, active) doctor — Dr. Shigeaki Hinohara of St. Luke's International Hospital — is 101 years old, and he's still publishing books and going on tours where he lectures mostly about how to live out your twilight years with health and happiness.

Unfortunately the good doctor is more the exception than the rule.
