• While a candidate's voice pitch sways voters, it doesn't result in better leaders

  14-03-2018 05:00
  (Florida Atlantic University) Studies show that people with lower-pitched voices are more likely to win elected office because they are believed to be superior leaders with greater physical prowess and integrity. But is voice pitch a reliable signal of leadership quality? And is the bias in favor of selecting leaders with lower voices good or bad for democracy? Researchers from Florida Atlantic University and the University of Miami are the first to address these questions in a new study.

  (R&D at British American Tobacco) Studies by British American Tobacco show that airway tissue damaged on exposure to smoke was restored when exposed to vapor from glo rather than smoke. These results add to evidence that glo has reduced risk potential compared to cigarettes. glo is a tobacco heating product designed to heat rather than burn tobacco. Tests show that glo heated tobacco vapor has around 90-95 percent less of certain toxicants than cigarette smoke.
