The first remarkable person, one you know, is Queen Elizabeth II.  Next year will mean 70 years as the reigning monarch, at the age of 95.  She is Queen to the UK, Canada, Australia, New Zealand, Jamaica and Barbados.  #2 in length is Hassanai Bolkiah of Brunei...53 years  They are prepared: I'm in the midst of planning three around the world trips.  Safety and security dominate my list of absolute needs.  I will avoid the summer heat of Dubai by walking through their World Expo in December.  I'm a bit concerned about the Buenos Aires World Expo because South American is just not a safe place these days.  I live in a cocoon. Then there is Sir Ranulph Fiennes.  Where do I start? In 1984 the Guinness Book of World Records named him as the world's greatest living explorer. To begin: His father died four months before Ranulph was born in the UK during World War II.  He inherited dad's baronetcy at birth. Grew up in South Africa but returned home to graduate from Eton Colleg
