Now if we could just do this exact same study on survivors to see if this would be a predictive test for our dying that would be any better than the other ones out there. Your doctor should have given you some type of test to tell you your chance of dying in x amount of time. And then if they were any good they would be keeping track of results to see if that prediction tool was any good. But that makes the assumption that your doctor is competent. Good luck with that.

Abstract
Objective
Studies
examining the relation of information processing speed, as measured by
reaction time, with mortality are scarce. We explored these associations
in a representative sample of the US population.
Methods
Participants
were 5,134 adults (2,342 men) aged 20–59 years from the Third National
Health and Nutrition Examination Survey (NHANES III, 1988–94).
Results
Adjusted
for age, sex, and ethnic minority status, a 1 SD slower reaction time
was associated with a raised risk of mortality from all-causes (HR =
1.25, 95% CI 1.12, 1.39) and cardiovascular disease (CVD) (HR = 1.36,
95% CI 1.17, 1.58). Having 1 SD more variable reaction time was also
associated with greater risk of all-cause (HR = 1.36, 95% CI 1.19, 1.55)
and CVD (HR = 1.50, 95% CI 1.33, 1.70) mortality. No associations were
observed for cancer mortality. The magnitude of the relationships was
comparable in size to established risk factors in this dataset, such as
smoking.
Interpretation
Alongside
better-established risk factors, reaction time is associated with
increased risk of premature death and cardiovascular disease. It is a
candidate risk factor for all-cause and cause-specific mortality.
