Kuba kukho ukhuphiswano, kuba kukho isilingo senzuzo; Ngoko ke kusoloko kukho izinto ezilungileyo nezimbi ezithengiswayo, kodwa ezinye izinto zinokuchongwa ngokukhawuleza, kwaye ezinye izinto kufuneka zichongwe ngononophelo ngexesha lokuthenga, kungenjalo ziya kuqhathwa. Umzekelo, iingxowa ezilukiweyo, xa kuthengwa, abathengi kufuneka bakhethe ngononophelo, siya kuqonda ukukhethwa kweengxowa ezilukiweyo ezikumgangatho ophezulu.
Ngokubanzi, iingxowa ezilukiweyo zinokwahlulwa kumbala kunye nokuvakala kwazo. Iingxowa ezilukiweyo ezenziwe ngezinto ezicocekileyo zihlala zikhanya ngokucacileyo kwaye zivakala zithambile ngaphandle kokubhoboza. Kodwa olu hlobo lwendlela kubathengi abaqhelekileyo alunamsebenzi, alungomgangatho, umlinganiselo wengxowa elukiweyo ubhekisa kubude bentambo ebotshelelweyo ngemitha nganye, iyunithi yi-g/m, kwizinto ezilukiweyo zentambo ebotshelelweyo, umlinganiselo wentambo ebotshelelweyo yi-3.5 g/m, umlinganiselo wentambo ebotshelelweyo ecocekileyo awuyi kuba mkhulu, kuba iimveliso zezinto ezicocekileyo zinokutsala inkqubo yemveliso inde kakhulu. Ukuba intambo ibotshelelwe, ubunzima obuthile buya kuba phezulu kakhulu kuneli xabiso. Oku kukwabangelwa kukongezwa kwezinto ezahlukeneyo.
Yingxowa elukiweyo elungileyo kuphela enokubonisa ngokupheleleyo iingenelo zengxowa, kungenjalo zonke iimpawu zayo zokusebenza ziya kunyamalala ngomgangatho ophantsi. Ngenxa yokusetyenziswa okukhethekileyo kweengxowa ezilukiweyo, kukho iimfuno ezingqongqo kumgangatho wazo.
