One could argue its because they 'clim'b trees.
I love that we are generally so laid back. There is nowhere near as much tension in the people as the US or Europe. Life overall is pretty good. No worries is exactly it. We are so far away from everyone we dont have any real enemies, we are developed so can buy whatever we like, we are young enough that there isnt a huge amount of negative history. Our industrial relations and laws are for the most part fair and just, applied evenly and it doesnt matter your nationality or wealth. Overall, life is good.
