Consider lust, the desire for sexual gratification. Lust is, for many people—and for males in particular, I think—a major distraction in daily living. We might be able to control whether or not we act on lustful feelings, but the feelings themselves seem to be hardwired into us. (If we lacked such feelings or could easily extinguish them, it is unlikely that we would have survived as a species.) Because they distract us, feelings of lust have a significant impact on how we spend our days.
