So many good facts about TONGA: it's been ruled only by kings called Tupou since 1845; King Taufa’ahau Tupou IV holds the record for the world's heaviest monarch (210kg / 460lbs); it's the only Pacific Island not to be colonised; it consists of 169 islands (nice); Paea Wolfgramm won the nation's only Olympic medal (1996, silver, super heavyweight boxing); they have the second-highest levels of obesity (second to Nauru only by 0.6%); in addition to its regular base-10 number system, there are at least four additional and independent number systems, depending on what is being counted (e.g. yams, fish, coconut, sugar cane). Amazing!
