Hands, not handwriting, can be very revealing of one’s character. In fact, it is the hands and not the eyes one could scrutinize to get a better insight of the person, experts say.
As far as occupations go, common sense tells us that a writer or an office worker is likely to have soft hands, while the expression "horny-handed son of toil" aptly reflects the damage done by manual labour.
To the great detective, Sherlock Holmes, such a theory was elementary. "By a persons' fingernails... by the callosities of his forefinger and thumb... by each of these things an individual's calling is revealed."
It was a lesson learned well by the Khmer Rouge, which ruled Cambodia during the 1970s. In a bid to root out individual thinkers, Pol Pot's soldiers would routinely examine people's hands. Those with soft palms were deemed "intellectuals" and despatched to the Killing Fields, writes Julian Joyce in BBC News Magazine.
Yet hands also allude to a person's age. A study by the American Society of Plastic Surgeons found that most people who were shown photographs of a female hand were able to accurately estimate the subject's age.
The most common giveaway, say researchers, is prominent hand veins, something that can be overcome - at least in the short term - by holding the hand up in the air so the blood drains away, says Steve Barker of the model agency Hired Hands. It's an old hand-model trick, and is routinely used to make a person's hands appear younger than they really are."
