Article: Not drying your hands thoroughly after washing them could increase the spread of bacteria, and rubbing your hands while using a traditional hand dryer could be a contributing factor, according to new research. The research looked at different methods of hand drying, and their effects on transfer of bacteria from the hands to other surfaces. The different methods included paper towels, traditional hand dryer, and a new model of hand dryer, which rapidly blows water from the hands. Our bodies naturally have bacteria all over them. However, bacteria from other sources, such as raw meat, can also survive on hands. They can be easily transferred to other surfaces, increasing the risk of cross-contamination . When the hands are washed, the number of the bacteria on the surface of the skin decreases, but they are not necessarily _ . If the hands are still damp then these bacteria are more readily transferred to other surfaces. The researchers quantified the effects of hand drying by measuring the number of bacteria on the hands before and after different drying methods. Volunteers were asked to wash their hands and palce them onto contact plates, which were then incubated to measure bacteria growth. The volunteers were then asked to dry their hands using either hand towels or one of the two hand dryers, with or without rubbing their hands together, and levels of bacteria were re-measured. The researchers found that rubbing the hands together while using traditional hand dryers could cancel out the reduction in bacteria numbers following hand washing. When hands are rubbed together during drying, bacteria that live within the skin can be brought to the surface and transferred to other surfaces, along with surface bacteria that were not removed by hand washing. A resaecher says, "Good hand hygiene should include drying your hands thoroughly and not just washing . The best method of drying your hands id using paper towels or using a hand dryer which doesn't require you to rub your hands together." Question: Which of the following results in the fewest bacteria after washing our hands? - Dying our hands using wet towels. - Dying our hands using paper towel. - Rubbing your hands when drying. - Air-drying our hands naturally.

Then he slowed down, watching out for children rushing out from between parked cars. As his car passed, no kids appeared. Instead, a brick smashed into his door! He slammed on the brakes (make his car stop). The angry driver then jumped out of his car, caught the nearest child and pushed him up against a parked car, shouting, "Who are you and what was that all about?" The little boy was full of apology, "Please,Mister... Please, I'm sorry...I didn't know what else I could do. I threw the brick because no one else would stop." With tears dripping down his face, the youth pointed to a spot just around a parked car. "It's my brother," he said. "He fell out of his wheelchair and I can't lift him up." Now weeping, the boy asked the executive, "Would you please help me to get him back into his wheelchair? He's hurt and he's too heavy for me." Touched beyond words, the executive tried to swallow the rapidly swelling lump in his throat. He hurriedly lifted the boy back into the wheelchair, then took out his fancy handkerchief and dabbed (a light touch) at the fresh scrapes and cuts. A quick look told him everything was going to be okay. "Thank you and may God bless you." The grateful child told the stranger. Shaken up for words, the man simply watched the little boy push his wheelchair-bound brother down the sidewalk toward their home. God whispers in our souls and speaks to our hearts.
