I've been told I am VERY literal; feel free to agree with that.

I googled the definition of "elderly," and it seems to depend on the context used.

Definitions of elderly on the Web:

aged: advanced in years; (`aged' is pronounced as two syllables); "aged members of the society"; "elderly residents could remember the construction of the first skyscraper"; "senior citizen"
aged: people who are old collectively; "special arrangements were available for the aged"

Old age consists of ages nearing the average lifespan of human beings, and thus the end of the human life cycle. Euphemisms for older people include advanced adult, elderly, and senior or senior citizen. Older people have limited regenerative abilities and are more prone to disease, syndromes, and sickness than other adults. For the biology of aging see Senescence.
en.wikipedia.org/wiki/Elderly

A person 55 years of age or older as defined by the New York State Human Rights Law, Section 296 of the Executive Law.

"Elderly" means a person or family as defined in the United States Housing Act of 1937, Public Law 412, 50 Stat 888, as amended. [1987, c. 737, Pt. A, §2 and Pt. C, §106 (new); 1989, c. 6 (amd); c. 9, §2 (amd); c. 104, Pt. C, §§8, 10 (amd).]

So if you live in NY, are age 55, and want that discount, then you are elderly!
