So you haven’t used your pepper spray in a decade or two? Guess what? It very likely still works and my guess is that it’s still throwing some serious Scoville units. Pepper spray is made from peppers. Those pepper extracts stay spicy when stored in that tiny little can. So if the can still fires, contents will still burn the bad guy. But remember, they will also burn you, and the danger of cross-contamination is real when deploying pepper spray.

If you carry pepper spray for self-defense, you might want to consider taking a hit yourself, just so you know how it feels and you don’t freak out if you have to deal with the pain during a fight.
