    Spending more than an hour on your smart phone each day may be a sign that you are suffering from depression,new study has suggested. The more time is spent  (use) a phone for any reason including texting and going online, the more likely volunteers werehave the blues.

    Monitoring people's comings and(go) using GPS tracking on their phones also helped track mood. Spending most of your time at home was also  (link) to depression, as was having an/a (regular) daily schedule, such as unusual shift patterns. “people are depressed, they tend to withdraw and don't have the motivation and energy to go out and do things,” said senior author David Mohr. “The data showed depressed people tended not to go many places (reflect) the loss of motivation seen in depression.”

    “The significance of this is that we can detect if a person has depressive symptoms and the severity of those symptomsasking them any questions. Phones can provide data obviously and with no effort on the part of the users.”

    Just How Buggy is Your Phone?

    What item in your home crawls with the most germs? If you say {#blank#}1{#/blank#} toilet seat, you're wrong. Kitchen sponges top the list. But cell phones are pretty dirty too. They contain around 10 times as many germs as toilet seats. People touch their phones, laptops, and other digital devices all day long, yet rarely clean them.

    In one incident, a thief paid a terrible price for stealing a germy cell phone. He stole it from a hospital in Uganda during a widespread of the deadly disease Ebola. The phone's owner reported the theft before {#blank#}2{#/blank#}(die)from the disease. Soon, the thief began showing symptoms and finally {#blank#}3{#/blank#}(confess)to the crime.

    {#blank#}4{#/blank#} in that unusual case a cell phone carried dangerous bacteria, not all germs are bad. Most cause no harm. In fact, they could provide helpful information. Look at the surface of your phone carefully. Do you see some dirty mars? “That's all you,” says microbial ecologist Jarrad Hampton-Marcell. “That's biological information.”

    It turns out that the types of germs that you apply all over your phone or tablet are different from {#blank#}5{#/blank#} of your friends and family. They're like a fingerprint that could identify you. Some day in the future, investigators may use these microbial fingerprints to solve crimes. Phones and digital devices may be one of the best places to look for buggy clues.

    In a 2017 study, researchers sampled a range of surfaces in 22 participants' homes, {#blank#}6{#/blank#} countertops and floors to computer keyboards and mice. Then they tried to match the microbial fingerprints on each object to its owner. The office equipment was easiest to match to its owner. In an {#blank#}7{#/blank#}(early)study, a different group of researchers found that they could use microbial fingerprints to identify the person who {#blank#}8{#/blank#}(use)a computer keyboard even after the keyboard sat untouched for two weeks at room temperature.

    One day, microbial signatures might show {#blank#}9{#/blank#} people have gone and what they have touched. They could prove {#blank#}10{#/blank#} an unmarked device is yours. So, sure, your phone is pretty germy. Does that inspire you, or does it just bother you?
