seniorhood 

The state of living as an older person senior citizen in our society. The experiences and attitudes associated with those over the age of 65. Ageism means the greater the likelihood that others will discriminate against older people just because they are older.
Seniorhood does not necessarily equal senilehood. Seniorhood is traditionally more revered in Asian societies than in American culture. A perfect synonym for seniorhood is elderhood, which happens to be the title of a new book by Louise Aronson, M.D. in which she celebrates older people and claims they are on average happier than younger adults.

Seniorhood can be a difficult period of life because of negative biases toward those 65 and over.
