so the culprit is concrete? we should hire some jackass to sit around and cure concrete all day then. or for that matter, have one of the idiots in the business school invent some concrete that cures in 1-2 minutes maximum. if the concrete cures in > 2 minutes, you get your money back that was paid for the concrete + a 20% bonus on top of that. also, you will get your name on a wall-of-fame at the concrete factory of people who's concrete took > 2 mins to cure.
i did some rough calculations and calculated that approximately 2 people (may be actually 1) per year may have concrete that > 2 mins curing time based upon the calculations i did about the concrete invention.
