Old Americans are separated into two classes．Retirement(退休)can
be either heaven or hell．“I do believe on the
whole the retiree(退休者)of
tomorrow will be wealthier and healthier than the same group of 30 years ago，”says Robert Friedland，director
of the National Academy on Ageing．“But
that's only part of the picture．”There is also a large
group whose household income hasn't been growing very much．For them the future is unhappy．
“Nature
is not always kind，”says Dr．Robert Butler，an expert in medical
care of old people，who was founding
director of the National Institute on Ageing．The
relationship between socio-economic position and life expectancy(预期寿命)has been known for a long time．Race is also connected．And
education is a powerful tool in lengthening life．
The reality is that poor people are sicker as they age
because they live in dirty neighbourhoods and have dirty jobs，they are left unprotected from environmental pollution，and the pressure of being poor wears down people's health，”according to Karen Davis，president
of the Commonwealth Fund，which studies health
issues．
“Cigarette
smoking has a great effect because it is more common in lower socio-economic
groups，”says Elizabeth Whelan，president of the American Council on Science and Health．“If you live in a state of hopelessness and helplessness and
don't think about the future，you are more likely to
take up life－threatening habits．”
“Race
and income have large effects on death，”a
team of researchers reported in the New England Journal of Medicine in 1996，after researching on 24 million whites and 2．1 million blacks．
With the exception(例外)of black women，the
highest income group had the lowest death rates and the lowest income group had
the highest death rates regardless of race．
For black women there was no consistent pattern across income
groups．
