Dr．Sylvia Earle wants you to stop eating fish．It’s not because fish are endangered, though wild fish stocks in many oceans are very low．It’s not because they're bad for you, though fishin many areas are exposed to poisonous substances in the water．It’s because they’re smart．

　　"Fish are sensitive, they have personalities,” says the marine biologist．For Earle, eating afish would be like eating a dog or a cat．“I would never eat anyone I know personally．”

　　There’s a lot more to fish than meets the eye：they talk to each other, they like to be touched, and they engage in behavior that can seem very human．They can remember things and learn from experience．Earle and a growing number of animal rights activists see these as strong arguments against eating fish altogether．

　　The activists also point out that fish feel pain and fish suffer horribly on their way from the sea to the supermarket．“While it may seem obvious that fish are able to feel pain, like every other animal, some people think of fish as swimming vegetables,” says Dr．Lynne Sneddon．“Really, it’s kind of a moral question．Is the enjoyment you get from fishing or eating fish more important than the pain of the fish?”

　　Fishermen and(fried)fish lovers are doubtful．“I've never seen a smart fish,” says Marie Swaringen as she finishes a plate of fish at a Seattle seafood restaurant．“If they were very smart, they wouldn't get caught．”

　　“For years, everyone’s been telling us to eat fish because it’s so good for us,” says another diner．“‘Now I’ve got to feel guilty while I’m eating my fish? What are they going to think of next? Don’t eat salad because cucumbers have feelings?”

　　See in your mind’s eye where you really want to be in ten years’ time．Choose your own values, activities, and relationships rather than copying others．Complete this exercise to learn what you really want in life．

　　While working with troubled teens, I used to have them do the Ten Years in the Future exercise．I asked them to write a letter to a friend as if it was ten years in the future．Most of these boys and girls didn’t think about the next week, much less ten years to come．Like the Cheshire cat says in Alice in Wonderland,“If you don’t know where you want to go, then it doesn’t really matter what road you take!”

　　Of course, this lack of“foresight”was a major reason their lives were pretty messed up．We had some great conversations as they really thought about what they wanted．For most of them, this was the first time they had ever thought this way!

　　But the real story is what happened to me．I did the exercise right along with them on many occasions, writing my dreams and visions in detail．In my letter to a friend, I had moved to the country, built my own home, authored a book, and started my own business working from home．

　　Over the next ten years, something magic happened．All my dreams and visions became a reality, almost as if arranged by an unseen hand．I realized that something very powerful was happening, more powerful than I realized initially(最初)．I did write books and start my business．We did move to the country and I did build my own home．

　　This letter to a friend will become a magnetic factor in your life．Your vision will guide you in your yearly goals, your monthly goals, and your daily activities．

　　You must write your letter as if it has already happened．For example：

　　“Leslie, I just wanted to make contact again and tell you about my life．I started my own gardening business in 2015 and it’s really taken off．”

　　“Dear Harold, I met the love of my life in 2016 and we moved to Hawaii where Frank works in a bookstore and I give surfing lessons everyday．We love it．”

　　Remember, describe all the details as if they have already happened．Write to a real person who you think you may still know in ten years．This will help make it more real for you．

　　Sit down and write your Ten Years in the Future letter today．

　　Japanese doctors have used thin sheets of tissue from people’s cheeks to repair damaged corneas(角膜)．A team from Osaka University transplanted thin layers of cheek cells onto the eyes of four patients with a rare and painful eye condition, reports BBC online．Patients whose vision had been cloudy could see well afterwards, and the“new corneas”remained clear more than a year after the operation．

　　Doctors can also take cells from a healthy eye and grow them in a dish to produce a new cornea, or they can transplant corneas from donors．But these techniques may not work when both eyes are too badly damaged by accident or disease．

　　The team hope their work may help solve the problem and lead to other types of grow-your-own tissue transplants．The cornea is the clear layer of cells on the surface of the eye．It cat be damaged by trauma(外伤)or by a range of diseases．

　　The team worked with four patients who had a painful condition that caused cloudy corneas and dry eyes．Often the eye can regenerate cornea cells but none of the four patients had this ability．The researchers took a 3mm-wide square of tissue from inside the mouth(cheeks)and grew it into a thin layer in the lab．They used a special low-temperature technique to separate a very thin sheet off each batch(组)．They then laid that onto the patient’s eye．The cell layers stuck onto the eye and developed into tissue that looked and acted like a healthy cornea．

　　However, long-term follow-up and experience with a large series of patients are needed to assess the benefits and risks of this method．“Yet, it does offer the potential of treating severe eye diseases that are resistant to standard approaches,”said the head of the research, Kohji Nishida．
