Article: Reseachers at the University of Kansas say that people can accurately juage 90 percent of a stranger's personality simply by looking at the person's shoes."Shoes convey useful information about their wearers,''the authors wrote in the new study published in the Journal of Research in Personality. Lead researcher Omri Gillath said the judgments were based on the style,cost,color and condition of someone's shoes.In the study,63 University of Kansas researchers looked at pictures showing 208 different pairs of shoes worn by the study's participants.Volunteers in the study were photographed in their most commonly worn shoes,and then filled out a personality questionnaire. Some of the results were expected:People with higher incomes most commonly wore expensive shoes,and flashier shoes were typically worn by outgoing people.However,some of the more specific results are strange enough.For example,"practical and functional'' shoes were generally worn by more "pleasant" people,while ankle boots were more linked with ''aggressive'' personalities.The strangest of all may be that those who wore' 'uncomfortable looking" shoes tend to have "calm" personalities.And if you have several pairs of new shoes or take extreme care of them,you may suffer from "attachment anxiety",spending lots of time worrying about what other people think of your appearance.There was even a political calculation in the mix with more liberal types wearing "shabbier and less expensive" shoes. The researchers noted that some people will choose shoe styles to mask their actual personalities,but researchers noted that volunteers were also likely to be unaware that their footwear choices were showing the deep side of their personalities.
Answer: People know little about their personalities.

Article: Time and how we experience it have always puzzled us.Physicists have created fascinating theories, but their time is measured by a pendulum and is not psychological time, which leaps with little regard to the clock or calendar.As some-one who understood the distinction observed, " _ Psychologists have long noticed that larger units of time, such as months and years, fly on swifter wings as we age.They also note that the more time is structured with schedules and appointments, the more rapidly it seems to pass.For example, a day at the office flies compared with a day at the beach.Since most of us spend fewer days at the beach and more at the office as we age, an increase in structured tune could well be to blame for why time seems to speed up as we grow older. Expectation and familiarity also make time seem to flow more rapidly.Almost all of us have had the experience of driving somewhere we've never been before. Surrounded by unfamiliar scenery, with no real idea of when we'll arrive, we experience the trip as lasting a long time. But the return trip, although exactly as long, seems to take far less time. The _ of the outward journey has become routine. Thus taking a different route on occasions can often help slow the clock. When was become as identical as identical as beads on a string, they mix together, and even months become a single day. To counter this, try to find ways to interrupt the structure of your day--to stop time, so to speak. Learning something new is one of the ways to slow the passage of time. One of the reasons the days of our youth seems so full and long is that these are the days of learning and discovery. For many of us, learning ends when we leave school, but this doesn't have to be.
Answer: Time is structured with too many appointments.
Why do units of time fly faster as we grow older?
