Health problems caused by a lack of daily physical exercise cost the world some $67.5 billion (61 billion euros) in 2013 -- more than many countries' GDP, researchers said Thursday.

By Amanda Becker and Jeff Mason PHILADELPHIA/WASHINGTON (Reuters) - President Barack Obama will paint an optimistic picture of America's future and give full-hearted support to Hillary Clinton in a speech on Wednesday to help her become the first woman elected U.S. president and stop Republican Donald Trump. On a day when Democrats meeting at their convention in Philadelphia planned to tout their candidate as far better suited than Trump to keep the country safe, the Republican gave his critics fresh fodder for attack with remarks that the Clinton campaign said posed a possible national security threat. Grabbing the spotlight at a news conference in Miami, Trump urged Russia to find and release tens of thousands of emails that Clinton did not hand over to U.S. officials as part of a probe into her use of a private email system while she was secretary of state.
