Debates, interesting way to listen on topic raised, discussed, with well prepared invited guests, timed clock with vote from audience. Over the years enjoyed listening to variety of debates.
Of late podcasting discussions are enjoyable, one has to listen to many points of view. Medical, Dr John Campbell delves into matters of interest. History, Neil Oliver from different angles of British history, sometimes tying in with current events.
Earlier years with Christopher Hitchens, IQ Squared debates, each country affects the next, try open ones mind to East/West, in Africa we are affected by both.
Too often we have a point of view, listening to both sides of a story assists in opening ones mind to possibilities from differing angles.
