Sensual Desire and Guarding the Sense Doors

Sensual desire is a hindrance and thus it should be avoided and preferably eliminated (though I'm highly skeptical whether something in the brain can really be "eliminated" regarding emotions - I doubt it.) But we humans have all day long sensual desires. Let it be for food, bodily comfort, music (sound), art (sight), sex, etc. So should we remove all of them (ideally)? Also what is meant by sense restraint? I cannot really fathom it. I doubt that it means to go out with closed eyes and ears, haha. Does it simply mean to avoid certain triggers? (which would answer the first question simultaneously) Thanks in advance
