When Guinness World Records editor Stuart Claxton is asked about world records, he is like a father who doesn't want to be seen as favoring one child over another.The venerable record-keeping organization has just released its list of top records for 2012 and Claxton insists all of them are important in their own way, whether it be the massive record Barack Obama set when 771,635 people retweeted his "Four more years" remark on election night or the death of Besse Cooper, who, before dying recently, was one of the 10 oldest people ever verified in history.Claxton is also impressed that the shortest male and female in the world met each other -- the first time in history that this has happened.
