[Although some people may consider this posting aid and comfort with the
 enemy, its not that I deny that people need vitamins.  It's just that most
 people who can afford Vitamin supplements have no need for them.]

From JAMA, Nov. 22/29, 1985 254:2894
Reproduced from Basu, TK, Schorah, CJ "Vitamin C in health and disease", 1981
