You might be a structural engineer if…
… you have pulled over the family car on vacation to photograph every detail of a bridge. Bonus points if this involved unsafe climbing.
… you have explained to your kids why it’s easier to open a bag of M&M;’s using Mode III fracture than Mode I.
… you think of headaches as a “thick wall pressure vessel” problem.
… you describe your time management philosophy as “moment distribution”.
… your 10 year old kid can pick up a row of books by compressing the sides and explain that this is how prestressed concrete works.
… you obsessively try to have your photograph taken on the top of the tallest skyscraper of every city you visit.
… you have instrumented your deck with strain gages to check for erosion of your backyard.
Okay, that’s all I got.
