The beautiful future-Mrs-Cameron shared this link to an online game called Spent with me, from one of her students. In the game, you have to try and survive for one month as an unemployed American with no savings.
It's a tough game, but underlines the sorts of tough choices and trade-offs that real people have to make every day. It's very Americentric (as you would expect), but if you have a spare few minutes, I suggest you try it out for yourself.
How did I go? Apparently, I could survive as a poor American since I got through all 30 days unscathed, but with what would have been a pretty wretched standard of living.
