Not me.
But yet another study has been done to show that aggressive behavior and enhanced risk taking, in stock trading and sports, can be predicted (somewhat) by looking at these finger lengths "because testosterone levels in the brain underlie both.."

Published January 13 in the Proceedings of the National Academy of Sciences, the study, conducted by University of Cambridge neuroscientist John Coates, suggests that biological traits may have as much or more to do with a trader?s success than do either experience or the ability to make rational choices. Men whose ring fingers are longer than their index fingers are exposed to greater amounts of testosterone in the womb, which may improve their rapid decision making skills
In his study, Coates examined the digit ratio of 44 male ?high frequency? traders in London who buy and sell securities, sometimes in amounts greater than $1 billion, but hold their positions for minutes, sometimes only seconds. He found that traders with a longer ring finger than index finger made more money.
?We were on the trading floor taking samples for another experiment, and I read an article about digit ratio and sports,? says Coates. ?I didn?t put too much stock in the measure, but we thought, ?Why not look at fingers?? We were shocked by the results.?
Exposure to high levels of testosterone before birth appears to make men more sensitive to the hormone as adults. In addition to playing a role in sexual functioning, testosterone has been associated with aggressive behavior and enhanced risk taking, and has been shown to predict performance in certain competitive sports.
Coates? findings are consistent with a Harvard study of testosterone and financial risk taking that appeared in the November 2008 issue of Evolution and Human Behavior. Using an investment game, the Harvard researchers found that higher testosterone levels correlate with financial risk-taking behavior.
?Research on digit ratios in relation to a number of behavioral and psychological traits has exploded in the past 10 years, but many of the findings have not been as convincing [as Coates?],? Coren Apicella, lead author of the Harvard study, said in an e-mail. ?Further study of biological markers and their relation to economic attributes will ultimately lead to a more comprehensive understanding of economic science.?
