&lt;p&gt;At 91 years old, Queen Elizabeth is celebrating 64 years on the throne. Born Her Royal Highness Princess Elizabeth of York on 21st April 1926, she became Queen aged just 25 when her father, King George VI, died.&lt;/p&gt;
                    &lt;p&gt;She is respected the world-over for her hard work and dedication to the role. in her 90th year, she carried out more public engagements than the Duke and Duchess of Cambridge and Prince Harry combined, and up until recently was patron of 600 organisations. It was  announced &amp;nbsp;in December 2016 that she will pass on some of her work to other members of the royal family to ease her own load.&amp;nbsp;&lt;/p&gt;
                    &lt;p&gt;In a speech on her 21st birthday, she said &quot;I declare before you all that my whole life, whether it be long or short, shall be devoted to your service and the service of our great imperial family to which we all belong.&quot;&lt;/p&gt;
                    &lt;p&gt;And she has truly lived up to that promise.&amp;nbsp;&lt;/p&gt;
                    &lt;p&gt;
                    The Queen has stolen our hearts over the years with her love of corgis, horseriding, gardening and a penchant for a gin before lunch. She&#x27;s stylish, articulate, thrifty and tough. Did you know she learned to drive during World War II to help in the war effort? And once allegedly drove a gobsmacked Crown Prince Abdullah around Balmoral estate (women are not permitted to drive in Saudi Arabia).&lt;/p&gt;
                    &lt;p&gt;From her wedding to Prince Philip, to her Coronation Day and the birth of her children, grandchildren and great-grandchildren, Queen Elizabeth has lived out her lives for the whole world to see.

                    &lt;p&gt;After all, as she once said herself, &quot;I have to be seen to be believed&quot;...&lt;/p&gt;
