Dear Cecil:
Coming home from a restaurant dinner tonight, the subject of tipping came up and with it many unanswered questions. Naturally, our thoughts turned to you, Cecil. (1) What is the origin of tipping? (2) Who determined the 15 percent figure? (3) Why do cabdrivers expect a tip when their job is to provide door-to-door service? I can understand giving a tip if the cabbie has to handle luggage, but they expect one regardless.

Cecil replies:
The origin of tipping is lost, like so many things, in the Mists of Antiquity. There's evidence that tipping goes back at least to the age of the Romans, but human nature being what it is, it could just as easily date from the invention of money.
Luckily for us, etymologists have managed to come up with a selection of deeply fascinating etymologies for the phrase "to tip." The dullest and most likely has it coming from the Latin stips, meaning "gift." In the days of Geoffrey Chaucer and Middle English, "to tip" meant simply "to give"--as in "tip me that cheate" ("give me that thing"), immortal words penned by one Samuel Rowlands in his 1610 Beadle of Bridewell.
The most charming explanation refers us back to the days of Dr. Johnson and his eighteenth century circle of wits. Upon entering his local coffeeshop for a session of epigram-flinging, Dr. Johnson (or rather, one presumes, his flunky, Mr. Boswell) would drop a few pence in a box labeled "To Insure Promptness" ("T.I.P."--get it?) in order to encourage a greater display of vigor on the part of the generally listless attendants.
Tipping spread from England to colonial America, but after the revolution it was frowned upon (temporarily) as a hangover from the British class system. One only tipped one's social inferiors, which, lest we forget, did not exist in the brave new world. Unfortunately, the working class eventually got around to swallowing its pride, and tipping returned with all the fervor it possesses today. Even the Communist countries have not entirely succeeded in eliminating the practice. These days, of course, taxi drivers and waitpersons depend on tips for a substantial part of their income. If you didn't tip, presumably they'd expect to be paid more, and your restaurant bills and taxi fares would consequently be higher. The fifteen percent standard is mostly a question of what the market will bear. In New York, the figure these days is twenty percent; European restaurants generally add a ten percent gratuity to the bill.

Exposing the body to sunlight and allowing vitamin D to pour in may help reduce the impact of influenza and other respiratory illnesses, reveals a novel study conducted by investigators at Greenwich Hospital and Yale University School of Medicine.
Maintaining a high level of vitamin D, in the range of 38 nanograms per milliliter or more, can reduce the probability of contracting ailments including nasal congestion, sore throat, and common cold.
Lead Researcher Dr. James R. Sabetta suggests, “since vitamin D is generally acquired through exposure to sunlight, there is a higher probability that people living in sunnier climate often have higher rates of the compound in their body, thus making them less susceptible to the influenza virus.”
198 adults studied
The research led by James R. Sabetta, MD, followed 198 healthy adults for six months during the fall and winter of 2009-2010.
The blood samples of the participants were measured every month using a 25-hydroxyvitamin D test, an accurate measurement of vitamin D levels in the body
However, the vitamin levels of the study group were not revealed to the researchers before the end of the study.
The participants were further asked to report any symptoms of a respiratory infection like nasal congestion, sore throat, cough with or without fever, chills, fatigue, and general malaise.
Results of the study
Out of the 18 people whose vitamin D levels were higher than 38 ng/ml, only three developed viral infections.
Of the 180 others, 81 participants, i.e. 45 percent, developed similar infections.
Those with better vitamin D levels showed a significant reduction in the number of ill days.
Supplementing with vitamin D to achieve a blood level 38 ng/ml or higher could result in a significant health benefit by reducing the incidence of viral infections of the respiratory tract, suggest the study researchers.
In their analysis paper, the team figured out that if a person had a vitamin D level of 38, the risk of allergycame down by 50 percent. "It is true that level 38 is just a little about what you should have to be considered in the sufficient range," Sabetta says.
However, further research is required to prove the effectiveness of vitamin D supplements in the prevention of the infections.
The study has been published in the peer-reviewed open access journal PloS ONE.
