Ngoba kukhona ukuncintisana, ngoba kukhona isilingo senzuzo; Ngakho-ke kuhlale kukhona izinto ezinhle nezimbi emakethe, kodwa ezinye izinto zingabonakala ngokushesha, kanti ezinye izinto zidinga ukubonwa ngokucophelela ngesikhathi sokuthenga, ngaphandle kwalokho zizokhohliswa. Isibonelo, izikhwama ezilukiwe, lapho uthenga, abathengi kudingeka bakhethe ngokucophelela, sizoqonda ukukhethwa kwezikhwama ezilukiwe ezisezingeni eliphezulu.
Ngokuvamile, izikhwama ezilukiwe zingahlukaniswa nombala kanye nokuzwakala. Izikhwama ezilukiwe ezenziwe ngezinto ezimsulwa zivame ukuba nokukhanya okusobala futhi zizizwe zibushelelezi ngaphandle kokubhoboka. Kodwa lolu hlobo lwendlela kubathengi abavamile luyinkosi embi, akuyona indinganiso, isilinganiso sesikhwama esilukiwe sibhekisela kubude bentambo yokubopha ngemitha, iyunithi ingu-g/m, ezintweni zentambo yokubopha ezihlanzekile, isilinganiso sentambo yokubopha singu-3.5 g/m, isilinganiso sezinto zentambo yokubopha ezihlanzekile ngeke sibe sikhulu, ngoba imikhiqizo yezinto ezihlanzekile ingadonsa inqubo yokukhiqiza inde kakhulu. Uma intambo iboshwe, amandla adonsela phansi aqondile azoba phezulu kakhulu kunaleli nani. Lokhu kungenxa yokwengezwa kwezinto ezihlukahlukene.
Isikhwama esihle esilukiwe kuphela esingabonisa ngokugcwele izinzuzo zesikhwama, ngaphandle kwalokho zonke izici zaso zokusebenza zizonyamalala ngekhwalithi ephansi. Ngenxa yokusetshenziswa okukhethekile kwezikhwama ezilukiwe, kunezidingo eziqinile zekhwalithi yazo.
