Text: Scientists, specifically biochemists, and martini connoisseurs have investigated the difference between a martini shaken and a martini stirred. The Department of Biochemistry at the University of Western Ontario in Canada conducted a study to determine if the preparation of a martini has an influence on their antioxidant capacity; the study found that the shaken gin martinis were able to break down hydrogen peroxide and leave only 0.072% of the peroxide behind, versus the stirred gin martini, which left behind 0.157% of the peroxide. Thus a shaken martini has more antioxidants than a stirred one. The study was done at the time because moderate consumption of alcohol appears to reduce the risk of cataracts, cardiovascular disease, and stroke.

Text: So far no team has yet managed to reach the championship game in their home stadium, or even come close. Only two NFL teams have reached the Super Bowl hosted in their home market: the San Francisco 49ers, who played Super Bowl XIX in Stanford Stadium, rather than Candlestick Park, and the Los Angeles Rams, who played Super Bowl XIV in the Rose Bowl, rather than the Los Angeles Memorial Coliseum. Besides those two, the only other Super Bowl venue that was not the home stadium to an NFL team at the time was Rice Stadium in Houston: the Houston Oilers had played there previously, but moved to the Astrodome several years prior to Super Bowl VIII. The Miami Orange Bowl was the only AFL stadium to host a Super Bowl and the only stadium to host consecutive Super Bowls, hosting Super Bowl II and III. MetLife Stadium, which hosted Super Bowl XLVIII, is the home stadium of two NFL teams: the New York Giants and the New York Jets.
