Secret to longevity?

You could joke about people feeling like they live longer in prison ...... but surprisingly, in the US, they actually do, at least blacks do and they skew the average.

State prison inmates, particularly blacks, are living longer on average than people on the outside, the government said Sunday.

* Inmates in state prisons are dying at an average yearly rate of 250 per 100,000, according to the latest figures reported to the Justice Department by state prison officials.
* By comparison, the overall population of people between age 15 and 64 is dying at a yearly rate of 308 per 100,000.
* For black inmates, the rate was 57 percent lower than among the overall black population -- 206 versus 484.
* But white and Hispanic prisoners both had death rates slightly above their counterparts in the overall population.
