In the 15th century you would have been lucky to live 35 years. In that era, Sultan Mahmud Begarha of Gujarat ruled for 53 years. In one account we find him, &ldquoA mountain of a man with a long moustache (that he tied above his head) and stately person, having an inordinate appetite.&rdquo Another, more vivid description, has him swallowing &ldquoa cup of honey, a cup of butter, and 100-150 bananas&rdquo at breakfast, and another 10kg of food during the course of the day. And oh, the Sultan made it a point to sleep with &ldquotwo pounds of rice&rdquo on either side of his bed, so he would have something to eat on whichever side he awoke.
