Why does Social Security consider my age in determining whether I am disabled?

Social Security has to consider age, because that is what the Social Security Act requires. As people get older, they become less adaptable, less able to switch to different jobs to cope with health problems. A severe foot injury which might cause a 30- year- old to switch to a job in which he or she can sit down most of the time, might disable a 60- year- old person who could not make the adjustment to a different type of work.
