Zizindikiro zakunja kwa bakha wamutu wakuda.
Abakha okhala ndi mitu yakuda amakhala ndi nthenga zakuda pabulu komanso pansi pake. Mutu, mapiko ndi kumbuyo ndizotulutsa. Mandible wapamwamba ndi wakuda ndi malire achikasu ndipo mandible wapansi ndi wachikasu. Miyendo ndi yakuda imvi ndi utoto wobiriwira wachikasu pambali pa tarsi. Akazi achikulire ndi akulu kuposa amuna. Mapiko a abakha achikulire ali ndi zamawangamawanga ndi zingwe zazing'ono zoyera, zomwe zimapereka kamvekedwe kofiirira kumapiko a mapikowo. Abakha achichepere okhala ndi mitu yakuda amasiyana ndi mbalame zazikulu ndi mizere yoyera yoyera yomwe ili pamwamba pamaso ndikutalika kuchokera kumaso mpaka korona.
Abakha okhala ndi mitu yakuda molt kawiri pachaka. Mu Ogasiti-Seputembala, mbalame zimasungunuka, ndikupeza nthenga zawo. Mu Disembala ndi Januware, nthenga zoswana zimasinthira nthenga zachisanu.
Kubalana kwa bakha wamutu wakuda.
Pa nthawi ya chibwenzi, amuna amatambasula khosi lawo, kukulitsa kukula kwawo mwa kukweza matumba am'magulu awiri ndi kumtunda. Khalidweli ndilofunika kukopa akazi. Abakha amtundu wakuda samakhala awiriawiri okhazikika. Amakwatirana ndi zibwenzi zosiyanasiyana, amuna ndi akazi. Ubale woterewu ndiwomveka, chifukwa mitundu iyi ya abakha sasamala za ana awo.
Abakha okhala ndi mitu yakuda ndi tiziromboti tosaza mazira. Akazi amaikira mazira awo m'zisa za mitundu ina.
Abakha am'nyanja amapeza zisa zomwe zili pafupifupi mita imodzi kuchokera m'madzi. Aliyense amaikira mazira awiri. Kukula kwa mazira ndi pafupifupi gawo limodzi mwa magawo atatu a mazira onse omwe abalalika. Abakha okhala ndi mitu yakuda amaswana kawiri pachaka, nthawi yophukira komanso masika. Sizimanga zisa kapena mazira ake. M'malo mwa abakha awa pezani mwini woyenera ndipo musiyire mazira pachisa chake. Abakha achikulire omutu wakuda samakhudza mazira kapena anapiye amtunduwo. Makulitsidwe amatenga pafupifupi masiku 21, nthawi yomweyi mazirawo amasungidwa.
Anapiye a bakha wamutu wakuda, patangopita maola ochepa atatuluka mu chipolopolocho, amatha kuyenda ndi kudzidyetsa okha. Kutalika kwa moyo wa bakha wamutu wakuda mwachilengedwe sikudziwika.
Komabe, makamaka, kupulumuka kwa ana ena onse a banja la bakha kumadalira pazinthu zambiri.
Kuchokera pa 65 mpaka 80% amphaka amphongo amafa mchaka choyamba. Nthawi zambiri, eni chisacho amazindikira mazira a anthu ena ndikuwasokoneza. Pachifukwa ichi, pafupifupi theka la clutch limatha. Mazira a bakha wokhala ndi mitu yakuda ndi oyera oyera, motero samabisala chifukwa cha utundu woyandikira, ndipo amawonekera kwambiri. Mbalame zazikulu zimakhala ndi mtundu wa nthenga, nthenga zawo zakuda ndi mawonekedwe osiyanasiyana zimathandiza kuti zisawoneke poyang'ana masamba obiriwira obiriwira. Kupulumuka abakha achichepere azaka chimodzi kumakhala nyama yolanda nyama zazikulu, koma kuchuluka kwakupulumuka kumawonjezeka poyerekeza ndi anapiye. Abakha ambiri omwe amafika msinkhu wachikulire amakhala mikhalidwe yachilengedwe kwa zaka 1 - 2 zokha. Kutalika kotalikirako kokhala ndi moyo m'banja la bakha ndi zaka 28.
Khalidwe lakuda la mutu wakuda.
Abakha okhala ndi mitu yakuda ndi mbalame zosamuka, zouluka m'magulu a anthu pafupifupi 40. Amadyetsa makamaka m'mawa, nthawi yonseyo amakhala pamtunda, amasambira masana kapena madzulo. Madzulo, zazikazi zimasaka zisa za anthu ena kuti ziikire mazira. Amakonda kuponyera mazira awo mu zisa zawo, chifukwa mtundu wa bakhawu umapezekanso m'malo am'madambo.
Blackheads sichiswana anapiye, kubereka kwawo kumadalira mitundu ina ya abakha yomwe imasakanizira mazira a anthu ena.
Izi zimakhudza ana a eni omwe samabereka ana awo. Amakhala ndi mphamvu zawo zowonetsetsa kuti abakha amisala yakuda abereka. Zotsatira zake, kuchuluka kwa mazira omwewo, abakha owerengeka amachepetsa ndipo kuchuluka kwa anapiye awo omwe amakhala ndi moyo mpaka zaka zoberekera kumachepa.
Popeza abakha okhala ndi mutu wakuda samaswana, sakhala mderalo. Mbalame zimadutsa malo osiyanasiyana kuti zikapeze chisa ndi munthu woyenera kapena pofunafuna chakudya.
Kudya bakha wamutu wakuda.
