Nthawi zambiri sitikumbukira khwangwala yokwezeka ndipo siwaphunzitse akakumana. Awiri akhwangwala awiri a ife - munthu m'modzi. Koma amasiyanitsa nkhope zathu mwangwiro, kuwaphunzira ndipo amathanso kufotokozera abale awo. Ngati munthu akhumudwitsa mbalame yoyipa, paketi yonse itha kuukira pamsonkhano wotsatira.
Gulu la asayansi ochokera ku Yunivesite ya Washington ku Seattle, lotsogozedwa ndi John Marslafff, adachita zoyeserera zingapo. Zotsatira zawo zatsimikizira kuti akhwangwala amakumbukira momwe munthu wina kapena munthu wina adatembenukira nawo ndikuchita mogwirizana.
Pakafukufuku wina, gulu la asayansi linkayenera kugwira khwangwala khumi ndi iwiri. Kwa mbalamezo sikunadziwe, anthu awa amavala masks apadera a latx omwe adatseka nkhope yonse.
Mbalame zokhazikika zimakhazikika mu labotale, komwe antchito wamba adasamaliridwa. Iwo adawasamalira, kotero akhwangwala adazolowera anthu ndipo amachita modekha. Izi zidapita milungu inayi.
Pambuyo pake, nthawi ina, anthu omwe ali mu mask omweo omwewo anaphatikizidwa m'malo omwe ali ndi mbalame, momwe asayansi adavalira khwangwala. Ndipo anali ndi nkhawa. Kusakanikirana kunawonetsa kuti nthawi imeneyo adayendetsa zigawo za ubongo pa mantha.
Kuyesa kwina kunachitika mumsewu, m'malo mwa mbalamezi. Mayi wina dzina lake Calley adalowa kudzadyetsa khwangwala, adamphunzira ndikuwuluka. Nthawi ina, pakudyetsa kumeneko, munthu adabwera mchigoba, yemwe adasunga akufa m'manja mwake. Mbalamezo zidadzutsa chidwi, kukana kukhala ndi chakudya cholosedwa ndikuyamba kuda nkhawa mlengalenga. Nthawi zina amayesa kumuukitsa munthuyu.
Pambuyo pake, ngati munthu atachoka pakudyetsa chigoba chomwecho, akhwangwalawa anakana kudya ndikuwonetsa nkhawa. Ngakhale kuti m'manja mwake analibe chilichonse.
Nthawi zingapo zotere ndi khwangwala adatuluka ndi munthu wokhala ndi njiwa. Koma mbalamezo zangochitika zokhazokha. Ndiye kuti, amakhala ndi nkhawa kwambiri za anthu omwe amawavulaza kwa abale awo.
Ndipo mmodzi wa owerenga athu nthawi ina adafotokozanso mbiri yake yaubwenzi ndi mbalame zanzeru izi. Msungwanayo adazirala khwangwala wina pabwalo, ndipo kamodzi pamaso pa mbalame adakhala ndi vuto la mnansi chifukwa cha malo ogona. Pambuyo pake, gulu lonselo lidayamba "bomba" galimoto ya wozunza. Chifukwa chake ndibwino kuti musakhumudwe.
Mudzatithandiza kwambiri ngati muuzana nkhani mu malo ochezera a pa Intaneti ndikuyika ngati. Zikomo kwambiri chifukwa cha izo. Lembetsani kuti musaphonye mabuku atsopano.
