Danny Hughes, who ran a crane at the now-closed Bethlehem Steel Mill for 24 years, sits on his porch in Bethlehem, Pennsylvania, U.S. April 22, 2016. After Bethlehem Steel's blast furnaces went silent 20 years ago in the city of Bethlehem, Pennsylvania, the local economy bounced back as new industrial parks filled with e-commerce companies and white-collar businesses fleeing New York's higher costs. That adds to the challenge for Donald Trump, Republican nominee for the U.S. presidency, as he seeks voters' backing in the state's primary on April 26.

A man crosses a main road as pedestrians carrying food walk along the footpath in central Sydney, Australia, August 12, 2015. Fast food may be falling out of favour in many countries around the world but companies are making healthy profits and boldly innovating in the unlikely market of Australia. Contrary to stereotypes of a beach-going community of fitness fanatics, official data out this week showed 40 percent of Australian adults are dangerously obese and have a poor diet that includes lashings of fast food. That makes Australia a hotbed for innovation by companies including homegrown firm Domino's Pizza Enterprises Ltd, McDonald's Corp and Yum! Brands Inc's, KFC and Pizza Hut as they struggle to win over health-conscious diners in other countries. Picture taken August 12, 2015. REUTERS/David Gray
