The link between smell and memory is powerful. In high school science class we had to smell things in small film canisters and write down a memory we associated with the smell. The only one I remember smelling is #12, which smelled like skunk spray. I wrote down "camp" even though I'd never had a skunk experience at camp. It just reminded me of cheesy camp movies. Now whenever I smell skunk I remember science class and the #12 film canister I took a hearty whiff of at my friend Rob's behest.
