IMO, if you can't take a ten minute break in a twelve hour day, you're doing a crappy job of managing your time. This is 2009- the macho stuff doesn't apply. No matter how much of a stud you think you are, you're subject to the same physiology that everyone else is. Sure, breaks won't come on a schedule like you'd get in a bank, and pace of sales dictates when they are, but no one should ever work for 8+ hours with no kind of break. In the US it's illegal, for starters. You may not take your breaks but if your employer doesn't permit them s/he will land in very hot water.
There's more to being a pro than hangin' N bangin' all night.
