'Where have all my friends gone?'  When Max Dickins decided to propose to his girlfriend, he realised there was no one he could call on to be his best man.  He quickly learned that he wasn't the only man struggling with friendships. For decades, countless studies from across the world have confirmed that men have fewer close friends than women - and the problem gets worse the older men get. But what goes wrong? And what can men do about it? Dickins is going to find out.  His funny and charmingly candid search takes him to the doors of world-leading experts. It forces him to examine the friendships he's had over the years, and where they have foundered. And, briefly, it sends him to the website 'Rent A Friend', where he pays someone to hang out with him. But let's not dwell on that.  Join Max as he takes a defibrillator to his social life. As he ultimately discovers that if he wants a Best Man, then he needs to be a better man.
