Zomwe zimayambitsa chiopsezo makamaka zinali kunenepa kwambiri, moyo wongokhala, kumwa mowa komanso kumwa mankhwala obwezeretsa mahomoni panthawi yosiya kusamba. Tsopano tikudziwa kuti zinthu zina zimathandizira kuti khansa iwonekere: Zinthu 27 zomwe zimakonda kwambiri khansa zalembedwa. Izi zikuphatikizapo mankhwala omwe amapezeka mu petulo, dizilo ndi zinthu zina zotayira galimoto, komanso zoletsa moto, zosungunulira, nsalu zosagwira madontho, zochotsera utoto ndi mankhwala ophera tizilombo omwe amagwiritsidwa ntchito pochizira madzi akumwa.
