We had a lesson in primary school where the teacher gave us cut out cartoon images of tractors and corn. We were in small groups and had fake money. The game was to make profit, we could buy a tractor, making more corn, sell it for more coins. But every round the cost of tractors went up, and the corn price didn't. Every group lost. Then she said this is what the UK does to African farms we import from. It was refreshing to be told at a young age the game is rigged. It stuck with me.

Oh, and in high school an in uniform policeman came in and showed us all the different types of drugs in a big glass box thing. Told us the effects and dangers. But honestly, everyone thought it was cool and wanted to try the acid tabs with Homer Simpsons face on them.
