Developmental eras in older adulthood is defined most often, as older adults - the elderly persons, golden-agers, senior citizens or "the old" are treated as if they were a single developmental cohort . However, recently, some writers have begun to make distinctions in older adulthood between the "young old (those from 65 to 74 years of age), the "old old" (those 75 - 84 years of age), and the "oldest old" or "very old" (those 85 years of age and older), even though these are properly chronological rather than developmental distinctions
