Welsh Journalist and the BBC's International Editor Jeremy Bowen has travelled around the world reporting on war and conflicts. His career spans over 40 years and has taken him to some of the world's most dangerous places. He says covering conflict ''leaves a massive mark'' but also finds the ''very best of human nature''. On this week's bonus episode of Walescast, he joins Felicity Evans and Bethan Rhys Roberts to reflect on his remarkable career and the personal toll of reporting in war zones.
