If a snake bites you, take a photo with your mobile phone! It may save your life. This is the surprising    41    of a British cook.
One day Henry Jackson was working in a restaurant kitchen. He picked up a dish from the table, and    42   a snake appeared ... and bit him on the hand.
A few days earlier, the snake came to the    43    from Asia in a box of bananas. It climbed out of the box and    44    under the dish.
“I went to try to pick it up and it bit me again, I threw it    45    the kitchen, and it landed in the fridge. So I closed the door,” Mr. Jackson said.
Anyway, Mr. Jackson stayed    46    and he took a photo of the snake with his mobile phone. Soon his    47    began to ache and he went to hospital. Then his chest began to hurt. Doctors couldn’t say what was wrong    48    they didn’t know what kind of snake it was.
Then Mr. Jackson remembered his mobile phone photo. The doctors    49    it to London Zoo. When they knew the kind of snake, they could give Mr. Jackson the right medicine, and he left hospital the next day.
“So my advice is this: If a snake bites you, pick up your phone. Take    50    photo first and then show the photo to the doctors,” suggests Mr. Jackson. “Oh, and if the snake doesn’t smile for the photo, don’t worry!”
