Seniors (Older people)

American heritage dict.: Usage note under 'Old' ("'Old'is the bluntest of the adjectives most commonly used in referring to advanced or advancing age. It generally suggests at least a degree of age-related infirmity, and for that reason it is often avoided in formal or polite speech. Many prefer 'elderly' as a more neutral and respectful term, but it too can suggest frailty, especially in reference to individuals as opposed to a group or population. And while 'senior' enjoys wide usage as both a noun and adjective in many civic or social contexts, it is often considered unpleasantly euphemistic in a phrase such as 'the senior couple living next door.' As a comparative form, 'older' would logically seem to indicate greater age than 'old.' Except when a direct comparison is being made, however, the opposite is generally true. The 'older man in the tweed jacket' suggests a somewhat younger or more vigorous man than if one substitutes 'old' or 'elderly.' Where 'old' expresses an absolute, an arrival at old age, 'older' takes a more relative view of aging as a continuum-older, but not yet old. As such, 'older' is more than just a euphemism for the blunter 'old', offering as it does a more precise term for someone between middle and advanced age. And unlike 'elderly', 'older' does not particularly suggest frailness or infirmity, making it the natural choice in many situations.")
