Odwala 2% okha ndi omwe adafotokozera zomwe akumana nazo monga momwe zimakhalira kunja kwa thupi. Kumverera komwe munthu amamva pafupifupi kudziwa kwathunthu komwe amakhala atafa.
Pafupifupi theka la omwe adayankha adati zomwe akumana nazo sizakuzindikira, koma zamantha.
Mwinamwake chofunikira kwambiri pakupeza phunziroli ndi cha bambo wazaka 57 yemwe amakhulupirira kuti ndiye woyamba kutsimikiziridwa zakuthupi mwa wodwala.
Umboni woyesedwa ndi madotolo
Atamangidwa mtima, wodwalayo adawulula kuti amatha kukumbukira. Zomwe zimachitika mozungulira mozungulira mwatsatanetsatane atamwalira kwakanthawi.
Dr Parnia adati: "Izi ndizofunikira, chifukwa nthawi zambiri anthu amaganiza kuti zochitika zokhudzana ndiimfa zimatha kukhala kuyerekezera kapena kusokeretsa. Zimachitika mtima usanaime kapena mtima utayambiranso bwino, koma osati zokumana nazo zomwe zimachitika 'zenizeni' pomwe mtima sukugunda.
"Pachifukwa ichi, kuzindikira ndi kuzindikira kumawoneka ngati zikuchitika munthawi ya mphindi zitatu pomwe panalibe kugunda kwamtima.
“Izi nzodabwitsa, chifukwa ubongo nthawi zambiri umasiya kugwira ntchito mkati mwa masekondi 20-30 kuchokera pamene mtima wayima ndipo suyambiranso mpaka mtima utayambiranso.
"Kuphatikiza apo, zokumbukira mwatsatanetsatane zakuzindikira pankhaniyi zinali zogwirizana ndi zomwe zidachitika."
