Young people frequently say that they want to exercise, but they just can't find the time. The solution just might be in-office interval training. Recent studies show that very short but intense exercise rapidly builds and maintains fitness and health, even when the workout is only a few minutes long. Work the stairs You can complete an excellent, effective -- and very brief -- workout in an office stairwell, says Martin Gibala, a professor of kinesiology at McMaster University in Canada and an expert on interval training. For a study that he and his colleagues presented earlier this year, they asked 12 out-of-shape women in their 20s to warm up for two minutes by slowly walking up and down stairs in a campus office building. They completed three of these abbreviated stair workouts per week for six weeks. By the end, their aerobic fitness had improved substantially, the researchers reported, by about as much as if they had been running or cycling each week for hours. Fidget your way to fitness. Parents and teachers may once have urged you to sit still, but wiggling, tapping your toes, standing briefly, and otherwise fidgeting as much as possible at your desk is in fact good for your body. In one recent study, college students showed healthier blood flow in their lower legs if they fidgeted than if they did not. Even better, a 2008 study found that among office workers, those who frequently fidgeted burned as many as 300 calories more each day than those who resolutely stayed still.

"When I grow up, I want to be..." Almost all of us have thought about, or been asked to think about, our future careers. Our answers may differ greatly. Even now your aspirations may have changed from when you were in primary school. However, it seems career options aren't only based on personal taste. In a survey carried out by Teens, doctors, lawyers, and bankers were some of most popular careers that people said they hoped to follow. This is in line with a similar survey carried out in the UK in May 2011 by job website monster. Co.uk, in which medicine was the top choice among UK teenagers aged between 13 and 17. Medicine and law are two of the oldest and best known professions. Their prestige may come from the fact that doctors and lawyers are some of the most esteemed members of society, and they make good money. Joining these high-profile professions is often seen as a sign of upward social mobility. It is equally unsurprising that banking is now one of the most common career choices. Youngsters worldwide think of banking and see the money rolling in. Wealth is increasingly becoming one of the most important indicators of a successful career. British young men list the UK tycoon Alan Sugar, Microsoft founder Bill Gates and Facebook chief Mark Zuckerberg as their top role models "for their wealth". Just as Chinese teenagers see being a banker as a good and fun pathway to "wealth". However, not every child has the makings of doctor, lawyer, or banker. They are those who see fulfillment and happiness in other areas, and many teenagers dare to ink more individuality into their career options. As the Teens' survey discovered, a variety of unconventional jobs---coffee shop owner, gourmet ,waiter at a fast food restaurant---are among teenagers' career choices. They can be equally interesting and rewarding jobs. With every choice comes responsibility and challenge, and all career paths require specific education and training, you have to learn to balance optimism and confidence with being realistic about your particular talents and skills.
