Teenager Jake Deham was skiing with his family in the USA when he fell over and lost one of his skis.His family didn ’ t know that he had a problem.They kept on skiing.When they got to the foot of the mountain,there was no sign of Jake. Jake couldn ’ t find his ski anywhere.In the end,he decided to take off his other ski and walk down the mountain.But he couldn ’ t work out the right way to go. It was now getting dark and he was a long way from any place of safety.He knew that he might die that night in the cold temperatures.But Jake kept calm.At home,Jake watched a lot of programs about living in difficult situations.He remembered the advice from these programs and knew that he should build a hole in the snow.He made a hole and pointed it up the hill so the wind couldn ’ t blow into it.Outside his hole,the temperature fell to a dangerous -15 °C that night,but inside it Jake was safe from the cold. But he had to get down the mountain.The TV programs always said, “ If you are lost , you should find someone else ’ s tracks through the snow and follow them. ” “ I wanted to live my life. ” remembered Jake. “ So I got up and I found some ski tracks and I followed those. ” He walked and walked and finally he saw lights.Nine hours after he lost his ski,he found a team of workers who came to save him.He was safe! His mum was very happy when she heard the news.Amazingly,Jake didn ’ t even have to go to hospital.He got through the terrible experience without any injuries. So,the next time someone says that watching TV is a waste of time,think of Jake. Sometimes TV can save your life!
