Kukura kwekuvhara iris kunonzi inosvika. Mamwe makamera anoyevedza achakubvumira kuti utonge uswa hwekuvhara. Izvi zvinokosha kune zvikonzero zviviri:
1. Kubhururuka kwakakura kunowedzera mune chiedza, kujekesa chiitiko chako nekuvandudza kushanda mumifananidzo yakajeka. Mukutaurirana, rutivi ruduku runoita mune zvishoma.
2. Kugadziriswa kwemavhenekeri kweropa kunokubvumira kugadzirisa kuwedzera kwebindu, kana kuti yakawanda yegadziriro inotarisa. Kuvhara kukuru kuchaita kuti zvinhu zviri mberi kwako zvakanyatsotarisa asi mamiriro acho akajeka. Chinhu chiduku chichaita kuti zvinhu zvose zvive zvakanyanya.
Makhamikari vanoita kazhinji vanoparidzira huwandu hwepamusoro - kureva kuti yakareba sei iris inogona kuvhura kuti vabvume chiedza. Izvo zvakakura, zviri nani.
