"Statistics show that of those who contract the habit of eating, very few survive." - George Bernard Shaw on confusing correlation with causation.

Regrettably, those who design our health care reform have failed to understand the difference between correlation and causation.  Increasingly, life extension statistical data is used in decision-making for seniors whether to grant them access to treatments.  Due to overall health decline and growing incidence of other health issues, cure-focused treatment life expectancy benefits decrease with age.  This purely correlation based statistics is misconstrued as evidence of diminishing with age causation, and access to treatments is denied.  Truly depressing....
