Highlining Will Kill You

“Any questions?”
Keith returns the cap to the Dry Erase marker, looking up from the large notepad for the first time in minutes. His ever-present maniacal grin is noticeably absent from his face, his whole body seemingly reflecting the seriousness of what he had just laid before me. I stare at the elaborate series of drawings Keith has just produced: each page depicts multiple formulas, schematics and ratios, circled and crossed out in a dizzying array of red and blue marker. Each drawing has enormous red arrows that point to the title of his presentation: “Highlining Will Kill You”. After 45 minutes straight of lecturing, I get the point loud and clear. I shake my head in defeat.
“OK, maybe this is a bad idea”.
