Nation-tans are as old as their country was founded or settled. They age only by the rate of human culture which is why America for example became an Adult in only a 20 year span. (pretty normal to us humans) while england was still a child when he was 200 or so years. Nation tans also only grow up to an adult stage. They become adults when they are finally recodnized as a country, territory or official settlement. Which is why Sealand is just a kid which is dangerous because if he isn't recognized as his own country and is forgotten about or if England disbans him he'll die. You'll never see a nation actually look like an old man (although some countries like japan feel the pain of their age being out of date so to say. It really depends on the health, economy and success of the nation at the time that determains their state of health and wellness.) because they are immortal until their country is disbanded, destroyed or forgotten by history. Such as the ancients, and religous groups like the Holy Roman Empire which is not actually germany like people like to think but a religious government that quickly suffered disbandment and was abandoned by it's own king. In which case it's rumored that a nation will live out the rest of their life in normal human years until they finally fade away from existence and return to nature. (although this is just a rumor) Some Nations avoid this by evolving into another mean. Prussia for example got his ass saved when he was united with Germany just before the tectonic knights disassembled and was revived when England split the brothers up after world war 2 into East and West. And the Roman Empire still exists because his homeland of Rome still abounds inside of Italy.
