Just randomly thinking of ways that skatboarding related knowledge and the lifestyle itself can help on a practical level.
Here are some I thought of:
-If the electricity goes out, there's a good chance you already have a stash of candles to burn
-If you are ever with somebody doing anything else and they sprain their ankle, you know exactly how to help
-If you are young and have an office job, when some older person asks what you did over the weekend you can skip over all the drinking and partying and just say "went skating with some friends" without being some creepy dude who just says "nothing"
