Abaphandi kwiYunivesithi yaseUnited States benza ingxelo yokuba iilekese zisekwe kwi-non-char, kwaye iindawo zayo azikho kwaphela. Babanga: Endaweni yokunika imvakalelo yokugcwaliswa, umzimba, ngokuchaseneyo, kuya kufuna okumnandi, oko kuya kuchaphazela inani.
Njengommiselo, iimveliso ezingaqumuki iswekile kwifom ecocekileyo zifundiswa zizigulana ezineswekile. Nangona kunjalo, kutsha nje intetho ephosakeleyo ivele yavela: "Ukuba uthenge izifuba zakho ozithandayo kwiglucose, ubunzima abuyi kukhula." Abaphandi babhengeza: Sukuthatha iilekese zolu hlobo kwabo bafuna ukunciphisa umzimba. Utolo esikalini luya kuqala ukukhula ngokukhawuleza.
Kuqhutywa isifundo: Ngaphezulu kwamadoda avavanyiweyo amashumi amabini kunye nabasetyhini abakwiminyaka eyahlukeneyo bafumana isiselo kunye neelekese zombini kwiswekile kunye nesiqhelo. Emva koko babonisa imifanekiso ngeZitya ezinomdla. Ngenxa yoko - abantu abasebenzisa iilekese kwi-fuctose babelambile ngakumbi.
Izazinzulu zafumanisa ukuba emva kokusebenzisa olu hlobo lweelekese kwingqondo yomntu, umsebenzi uyakhula. Yintoni ekhokelela kumnqweno wokutya isidlo.
