Japan’s standard of living and medical care available gives them a life expectancy of 84 years. Akira was also successful and rather wealthy by the standards of his country and thus had a access to an even better standard of living than most.

Life expectancy also takes into account infant mortality and young deaths - if overall life expectancy is 84, and you’re already 68, you would likely make it longer than 84 since you already didn’t die for the first 68 years.
