You're officially old at age 57, according to new research.
A survey of 2,000 Americans pinpointed the age at which people consider themselves old, and revealed it to be a few years before the big six-oh.
More than just looking at what age is "old," the survey also delved into respondents' worries as they age, and found there's more to think about than just grey hair and wrinkles.
Commissioned by LetsGetChecked and conducted by OnePoll, the survey revealed respondents' overall health to be their top concern.
In addition to their overall health, respondents' worries included not being able to take care of themselves (34%), being seen as "old" (33%) and having financial security (33%) as they age.
