We're living longer -- is that a good thing?

The San Francisco Chronicle reports:

People born at the turn of the 20th century lived an average of 47.3 years, according to tables published by the National Center for Health Statistics. People born in 1950, however, can expect to live 68.2 years, and those born in 2003 can look forward to 77.6 years of life.

It will be interesting to see how all of this plays out.An increasing healthy group of people, with advances in modern technology, may live to over a hundred.Many children who grow up eating junk food diets and having weight problems,at an early age,will probably not make it to 65.Anyway,how this will move the averages one way or another is anyone's guess.
