I returned home the other night, tired. My husband asked me how my evening was, “Great.” I told him. I had spent 90 minutes in a gym with 10 Ping-Pong tables and all kinds of players, all playing a little ball over the net. By 9 pm, I was excited, tired, satisfied. I had beaten two young men half my age and lost battles against other competitors. To an observer, the night was common. To me, it was a lucky thing that I hadn’t expected.

I had taken up Ping-Pong during college, and in my 30s took more advanced lessons. However, a serious accident hurt my leg, which made me unable to take exercise. Months later, I tried to play Ping-Pong but my leg pained for a week. I put the game out of my mind.

When I was 53, one day my bad leg was working a little bit better. Could Ping-Pong be possible for me, now---in my condition, at my age? I tried to play Ping-Pong again

Ping-Pong is a sport which requires endurance(耐力). Players need quick foot work and upper body movements to return balls, requiring faster response time than tennis.

Playing Ping-Pong offers benefits for the brain. A study of 164 women aged 60 and older showed that Ping-Pong improved cognitive(认知)function more than dancing, walking or gymnastics. “The great thing about our sport is that it can be played by anyone,” said Jimmy Butler, a four-time national USA Table Tennis Association winner. “I see 90-year-olds and 10-year-olds.”

Years passed and my endurance improved. People started to praise my shots. I won a game. Then I won agin. These days, I feel wonderful, I believe this sport is the fountain (源泉)of youth.

At least five wolves, including one female, have returned to Denmark for the first time in two centuries, a zoologist who has obtained DNA evidence said on Thursday.

The wolves came from Germany to settle in western Denmark's agricultural region, the least densely populated in the Scandinavian country. Peter Sunde, a scientist at the University of Aarhus, told AFP the wolves must have walked more than 500km. "We think these are young wolves rejected by their families who are looking for new hunting grounds," the researcher added. Scientists have established a genetic profile from the faeces(f粪便) of five wolves - four males and one female - but there could be more. Sunde said researchers had suspected since 2012 that wolves had entered Denmark. "Now we have evidence [including] that there's one female," signalling the possibility of giving birth this spring, he said.

Proof was also established through the wolves' fingerprints and video surveillance(监视,监督) showed their location, which scientists refuse to reveal out of fear that it will attract hunters."We're following that. The wolf is an animal we're not allowed to hunt so we must protect it," said Henrik Hagen Olesen, spokesperson at the Danish Environmental Protection Agency.Exterminated by hunters, wolves had been completely extinct in Denmark since the beginning of the nineteenth century.

In other Nordic countries with a higher wolf population, culling(选择性宰杀) the species, protected by the Bern Convention, is under a fierce debate between inhabitants, farmers, hunters, the government, the European Union and wildlife activists.

Don’t you just hate it when you have to take an important phone call but you’re surrounded by potential eavesdroppers (偷听者)? You either have to whisper or go outside to keep the conversation private, which does not feel good. Now Hushme aims to fix this problem by muffling your voice and making you look like Bane in the film Batman.

Hushme is a strange high-tech mask (口罩) that blocks the sound of the wearer’s voice so that people nearby can’t hear what is being said. It connects to your phone via Blucetooth and comes with a pair of earphones. When you get a private call, all you have to do is put the mask on and it will do the rest. The pair of thick pads over your mouth does a good job of muffling your voice, but to ensure nothing gets through. Hushme also has speakers that play a variety of sounds when you speak.

The Hushme mask, which comes in a variety of colors, can be worn around the neck, like a regular pair of earphones, and attaches in front of your mouth thanks to a couple of very powerful magnets (磁铁). It’s not yet clear how comfortable speaking with this Bane-like mask over your mouth really is, or how effective its speech muffling ability is, so we know so far is that it makes you look strange. The sound choices for covering your voice currently include wind, ocean, rain, birds, monkey, but new ones could be added in the future.

Advertised as the “world’s first voice mask for mobile phones’. Hushme was showed at CES. At the becoming of this year. Its makers plan to sell it by the end of this year. It will cost about $200.
