From this site: http://en.wikipedia.org/wiki/Okinawan_martial_arts, I googled and read about the lifespans of 12 biggest names in Shuri-te and 12 biggest names in Naha-te ( Gōjū-ryū and Tōon-ryū). On average, Shuri-te artists died at the age of 80.4, and Naha-te artists died at 74 y.o. However, one difference is that most of the life time of Shuri-te artists don't include the mal-nutrited Japan's post-war period.
