Genetic factors such as race, skin tone and gender can also drastically affect the likelihood of getting skin cancer. There is a growing concern among researchers that people may develop a false sense of security when using sunscreens because they can spend more time in the sun without getting burned. Cases of melanoma have increased from 5.7 per 100,000 in 1973 to 12.5 per 100,000 in 1994. More than one person in Texas will die each day from melanoma. In 1996, Texas ranked second highest among states in skin cancer rates, behind California.
Scent can be a powerful tool to lure shoppers and sell merchandise.
Scent influences a buyer's selection of soaps, lotions, colognes, perfumes, and many other items, even dishwashing liquid. Often, the sense of smell can break through the verbal and visual morass of marketing. Products without a scent may be equally consequential to some customers. Electronic noses show great promise in detecting explosives and drugs, monitoring pollution, and even diagnosing diseases. In some climates, half the cost of ventilation occurs during the 30 hottest or coldest days of the year.
