We all know that fatherhood has changed over time, but how do dads feel about it? Jeremy Macvean is the co-editor of The Father Hood, Inspiration for the New Dad Generation. It's a book that combines the stories of celebrity dads like Barack Obama and Mark Wahlberg with the research and knowledge of dad advocates Steve Biddulph and Professor Richard Fletcher. Jeremy talks about what is different for fathers today, and why this offers the greatest opportunity men have seen in generations.
