Q: Article: Compared to high heels , they don't look dangerous, but flip-flop wearers should think twice before slipping on a pair. The National Health Service spends PS40 million a year treating injuries caused by wearing the casual footwear. More than 200,000 people end up in hospital every year after suffering falls or developing long-term problems. Once worn only at the beach, flip-flops have become the regular summer footwear of choice for women, with two in five women owning at least one pair. But experts are warning the public of the dangers of wearing flip-flops, such as the risk of joint pains. They say flip-flops force people to change the way they walk so that when taking a walk with long steps they put pressure on the outside of their foot, rather than their heel, causing long-term damage. And there is also the risk of serious injury. Frequent complaints include twisted ankles, but some have broken their arms or wrists after falling because their flip-flops caught on uneven ground. Many also suffer aching toes as they constantly wear them. Mike, a spokesman, warned wearers of the damage done by flip-flops. He said, "They land on the outside and then roll the foot inwards putting all the pressure on the big toe." This constant rolling puts pressure on the ankle joint, causing it to weaken. The lack of support of the flip-flop also causes pain on the inside of the foot and lower leg. And if you're not used to wearing them, they can cause blisters , he added. Doctors say flip-flops cause far more damage as they are worn for longer periods of time. Emma Supple, consultant podiatrist , said, "Flip-flops are universally popular. They are easy to put on and easy to wear but women do need to be mindful that wearing on hard flat surfaces can cause considerable foot and leg problems." She encouraged women to wear suitable shoes to help recover from summertime injuries.

Q: Article: Last week, I bought an alarm system for about $ 450. It consisted of a control unit with three other small units. I put the control unit in the sitting room and fastened the other units by the front door, back door and living-room windows. The instructions told us to choose three numbers, so we chose 491, the last three numbers of our telephone number. Now I must explain how the alarm works: 1. There is a power siren in the control unit. It makes a very loud noise. 2. Each of the small units sends out beams or rays in different directions. If anything moves, it breaks a beam. This sends a signal to the control unit. The siren makes a noise that you can hear 50 meters away. 3. When we go to bed, I press the three buttons numbered 4, 9 and 1. Then we have 30 seconds to get out of the room before the alarm starts to work. That might I slept soundly because I was sure that no burglar could get into our house. However, at about 2:10a.m., I woke up and heard the siren . "There must be a burglar in the house," Mary said. "What shall we do?" "I'll go and see who's there," I said. "Stay here. Don't make a noise." I went downstairs quietly. When I reached the living room, I switched on my torch and looked round the room. Then I turned the light on. I switched the siren off and searched the rooms downstairs. There was nothing wrong except that the back door was unlocked. I locked it, re-set the alarm and went back to bed. About an hour later, the alarm started again. I jumped out of bed, fell over a chair in the dark and bumped into the bedroom door. Mary woke up and started hitting me with a torch. "Hey! Wait a minute!" I whispered. "It's only me. I' m going downstairs to see what's wrong." I went down into the living room and listened for a moment. The only sound I could hear was the siren. I turned on the light and then switched the siren off. As I did so, I glanced across at the curtains in front of the windows. I saw a house lizard disappear behind the curtains. "Oh!" I said to myself. "That's our burglar." When the lizard moved, it started the siren. I guessed that the alarm had been made in Europe, where there are no house lizards. Well, I won't finish this story but if you want an alarm system free of charge, let me know. I'll send you ours. We bought a dog this morning. It knows the difference between a lizard and a burglar.
