Note2 that the total surface area of the nail points is 1/10 that to receive good pain, as this bed is very much suited for one who either desires bad pain, or might it be that this person feels no pain after 20 years of pain that is not noticed anymore as like when one inside a house reading a book while outside the near open window is a very loud gasoline engine grass cutting machine working and then later the grass is all cut and only when the machine is turned off does the book reader notice it. As if he got use to the noise and does not hear it anymore until it stops and then he hears silence. (a.k.a. goldbugs) No pain, no gain Scientists linking physical pain and pleasure to investor buy and sell decision By Dolores Kong, Globe Staff, 12/10/2000 AMBRIDGE - It looks like an outfit only the Marquis de Sade could love. But the black body suit, with water hoses running through it, isn't an instrument of torture. It's a research tool for understanding the peculiar suffering investors have come to know all too well in recent weeks: watching the stock market plunge, regain some ground, and then cascade ever lower. Dan Ariely, a professor at the Massachusetts Institute of Technology, uses the specially designed two-piece synthetic suit, along with computer stock market simulations, online surveys, and other methods, to investigate the agony - and the ecstasy - of participating in the markets. By better understanding the pain of investing..... In the pain/pleasure lab, Ariely demonstrates how the heavily ribbed garment works..... On the computer, a simulated stock market crash represents..... But Ariely, a specialist in both psychology and marketing, sees remarkable parallels in the two kinds of suffering. ... people's perception of pain depends on the pattern of the pain. For instance... or if the stock market crashes near the end of the trading day - that's harder to take..... Should an investor sell everything and take the losses, or... buy beaten-down... or unplug the tube? The growing body of behavioral research suggests..... ... if investors realize what pains them, they won't..... For instance, if investors know that research has found... ... perhaps they won't... in a knee-jerk reaction..... The brain sends us all kinds of signals, fight or flight... book, "Beyond Greed and Fear"..... "Our mind interprets signals from financial markets as if we're in the days of the hunter-gatherer. We haven't evolved enough so that our emotional side knows the difference." Shefrin said. ... has often found a desire for pain - or the desire to avoid it - to be a driving force behind buy, sell, or hold decisions. ... may also hold on to their laggards because they don't want to see the stock price skyrocket after they sell for a loss. ... there can be pain even when people sell for a gain. ... helped coin the phrase "disposition effect" to explain this strange behavior by investors of selling their winners too early and riding their losers too long. ... people who trade frequently tend to be more overconfident, have a less stable sense of self-esteem, and worry more about their trades. ... they feel the pain of a market meltdown more intensely. Ariely's bottom-line advice to numb the pain? "It's better not to look at the stock market when it's not doing well."
