The label "senior citizen" is often applied to Americans age 65 and older. Many retirement programs kick in at this age. Senior citizens also receive discounts on purchases at some restaurants and retail stores. A Pew Research study in 2009 indicated that the average respondent believed old age starts at 68. The survey also showed that older people believed old age started at a later point than younger respondents.

    Why are there 365 days in a year instead of 364?

    One year is measured by the time it takes a planet to orbit the sun, and 365 days is the best estimate for how long it takes Earth to complete a full trip around the sun. Years on other planets are measured in comparison with the Earth year, and one year on most planets is longer than one year on Earth.
