Komabe, izi sizikuyambitsa mavuto ndi zovuta zina. Izi zili choncho chifukwa chakuti makina othandizira amalumikizana ndi kayendetsedwe ka ophunzira, kotero palibe kusokonezeka kwa chithunzichi.
Kuonjezerapo, makina ojambulira ndi operewera kwambiri kuposa magalasi m'moyo wa tsiku ndi tsiku. Mungathe kupita nawo ku masewera, kumasuka mu chilengedwe kapena kupita kuntchito, mukuiwala kuti muli ndi mavuto. Ubwino uwu ndi wofunika kwambiri kwa anthu ogwira ntchito omwe safuna kuyang'ana magalasi oyenera nthawi zonse kapena kuyesa kuti asaiwale penapake.
