The inherent qualities of chips—fat plus salt—encourages you to keep eating chips. This is especially a problem if you sit down with an open bag, as opposed to putting a single serving of 10-12 chips on a plate (sad, but necessary). This problem of endlessly eating chips is exacerbated by fiery spice on the outside of the chips because the hotness is yet another lever that makes you keep eating. But at some point the heat gets overwhelming and your tingling lips, runny nose, and burning fingers cause you to stop.
