Only half of Australians say they would fight for the country if we were under attack. What does that say about our social contract? Who feels part of the "we" that makes up our nation? Is patriotism destined to die when the promise of "a fair go for all" isn't guaranteed anymore?

Alcohol death rates in Europe. Apparently very low in cultures where drunkenness is frowned upon and where alcohol is only consumed in company of others and served alongside meals. Spain and Italy for example. Source: buff.ly/3wDQcRz

I like the idea of visiting all countries that fall within “your” 10% slice of the world. See how your fellow 10% live.
