We’ve been covering standing desks for a long time now because experts agree that sitting all day is killing us.We want to be productive while also keeping our bodies healthy.Over the years,there have been several solutions to this from fixed standing desks to adjustable ones,portable desks to ones that change into shelves.

However, the most high tech and elegant solution has to be this new smart desk called The Stir Kinetic Desk.The desk learns your daily behaviors and moves between a sitting and standing height regularly throughout the day to keep you moving without interrupting your work flow.

You can program specific sitting and standing intervals or let the desk set the schedule.If you tend to sit while returning emails in the morning,but always want to stand during that afternoon conference call,the desk will learn those regular habits and adjust the schedule to fit them. Of course,the desk can always be manually lowered or raised by using the touch screen on the lower left comer of the desk.

When switching positions,the desk gently dips and rises to let you know that a change is coming up.If you’re not ready to switch positions at that time,you can tap the touchscreen to stay sitting or standing for a while longer.

The built.in touchscreen also keeps track of your daily sitting and standing times and tells you how many calories you’ve burned.You can even set goals for how long or often you want to stand.The desk also works with fitness devices like the FitBit to track your movements.

All of that smart tech doesn’t come cheap though.The M1 desk,which is the everyday model,runs a steep $2,990,while the more executive model with added features,the F1,goes for$4,190.

While expensive,it’s worth thinking of how much time we spend at our desks.Much like a good mattress(床垫),a good desk that works with you is worth the investment.Hopefully in a few years these smart,integrated desks will be more common and less expensive.

If you are sending a text message, watching TV or listening to the radio, you may stop and give this your full attention. Multi-tasking shrinks(使……萎缩) the brain, research suggests.

A study found that men and women who frequently used several types of technology at the same time had less grey matter in a key part of the brain. University of Sussex researchers said, “Using mobile phones, laptops and other media devices simultaneously could be changing the structure of our brains.”

Worryingly, the part of the brain that shrinks is involved in processing emotion. The finding follows research which has linked multi-tasking with a shortened attention span, depression, anxiety and lower grades at school.

The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology. This could mean sending a text message while listening to music and checking email, or speaking on the phone while watching TV and surfing the internet. The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingulated cortex (ACC) (前扣带皮质). Scientists have proved that brain structure can be changed on exposure to fresh environments and experience.

Other studies have shown that training – such as learning to play magic tricks or taxi drivers’ learning the map of London – can increase grey-matter densities(密度) in certain parts.

Experts have also warned of the harmful impact technology can have on our memory and attention span. The University of California team conducted a survey of more than 18,000 people aged between 18 and 99, and found 20% had problems with memory. Researchers were shocked greatly by the 14% of 18 to 39-year-old people who also worried about their memories.

Multi-tasking may shorten attention span, making it harder to focus and form memories, the researchers said, adding that youngsters may be particularly affected by stress.

B. Students’ doing their homework.

C. Taxi drivers’ learning the map of London.

D. Speaking on the phone while watching TV.

4.Which of the following can be the best title of this passage?

B. Multi-tasking shrinks the brain.

C. Multi-tasking may shorten attention span.

D. People are worried about their memories.
