My chiro suggested fun activities for stress too (video games count).

My friend got hammered by fees at a currency exchange in Madrid last year. He was desperate for cash after his bank card got blocked overseas. The posted rate seemed fair, but hidden charges took a huge bite out of his money. He ended up with so little cash that he almost couldn't pay for his train ticket. It was a harsh lesson about always having a backup plan when traveling. Those airport kiosks really do squeeze every last cent from you.

Seriously, missing a hidden rust spot is the worst feeling. I learned the hard way to always check inside with a boroscope now. It stops those annoying comebacks after you seal everything up.
