Titsutsani Makolo Athu a Misozi Yowawa
Mano amzeru (kapena katatu) ndizovuta. Nchifukwa chiyani ife timapatsidwa mano omwe, nthawi zambiri, amangomaliza kukopa? Ngakhale kuti mano amasiku ano ndi anthu amantha omwe akuopa, ntchito ya nzeru zapamwamba imabwerera kwa makolo athu oyambirira.
Chifukwa Chake Timapeza Malangizo Amtima
Makolo athu akale kwambiri anapulumuka pa chakudya chambiri, mtedza, mizu, zipatso, ndi masamba.
Mamuna wa Mag-Magnon analibe mwayi wambiri pogwiritsa ntchito mipeni kuti adye ndi kukonzekera chakudya chake komanso kuphika nyama yake. Kudula zakudya zopweteka, zowopsya komanso zovuta, zimafuna nsagwada ndi nsonga zolimba-kuphatikizapo mano anzeru.
Kukhala ndi malipiro onse atatu kunali kofunikira kuti makolo athu athe kudya zakudya zofunika kuti apulumuke. Nsagwada zazikulu zomwe zinali zofala kwa makolo athu zinkakhala mosavuta mano a nzeru. Izi zinawathandiza kuti azilowetsa pakamwa.
Kufalikira kwa mano a nzeru ndi njira imodzi imene akatswiri a anthropologist amatha kudziwa zaka za mafupa. Mwachitsanzo, mafupa a "Turkana Boy" ku Smithsonian National Museum of Natural History anafika zaka 1.6 miliyoni zapitazo. Ochita kafukufuku amakhulupirira kuti anali ndi zaka zisanu ndi zitatu kapena zisanu ndi zinayi, chifukwa china chake chinali chakuti chotsatira chake chachitatu chinali chisanasinthe pamene anamwalira.
Chifukwa Chake Sitikusowa Nzeru Zambiri Masiku Ano
Yambirani mofulumira lero ndipo yang'anani zomwe tikudya.
Chofunika kwambiri, yang'anani momwe timakonzekera chakudya chomwe timadya.
Timadula, timadula, timaphika, timaphika, timatentha, timaphika pafupifupi zonse zomwe timadya. Zonsezi zikukonzekera kuti chakudya chikhale chosavuta kwambiri kukwaniritsa. Ndipotu, akatswiri amakhulupirira kuti jawline yathu yayamba kukhala yaying'ono komanso yaying'ono pazaka zambiri chifukwa cha momwe chakudya chimakonzedwera ndi kugwiritsidwa ntchito.
Ndicho chifukwa chake mano athu a nzeru amafunika kutengedwa.
N'chifukwa Chiyani Nzeru Zimakhala Zovuta?
Monga momwe anthu amakono amakonzera, dongosolo lathu lonse linasintha. Patapita nthaŵi, fupa linakhala laling'onoting'ono ndipo mano onse 32 sakanatha kukwanira bwino. Monga nzeru zimayambira mano amatha kukakamiza mano ena ndipo amachititsa mavuto. Ena amakhalanso "okhudzidwa" ndipo samatha kwathunthu chifukwa palibe malo ndipo amatsekedwa ndi mano ena.
Sikuti aliyense ali ndi mano a nzeru, komabe. Zosachepera, sizikhoza kuyendayenda mopitirira pamwamba. Pali zifukwa zingapo izi, malinga ndi ofufuza . Izi zikuphatikizapo kukula kwa mizu ndi kukula kwa dzino, kukula kwake, ndi malo omwe alipo mu nsagwada.
Ngakhale kuti mano a nzeru sali ovuta pakamwa, amatha kupeza mano aukhondo pofuna kupewa zinthu zamtsogolo monga chitukuko cha matenda. Mankhwalawa ali kutali kwambiri pakamwa kuti kuwasamalira bwino kungakhale kovuta. Dokotala wa mano akhoza kulangiza wodwala kuti atenge mano awo a nzeru kuti azitha kukhala ndi thanzi labwino.
N'chifukwa Chiyani Amatchedwa "Nzeru"?
Nthano zanu zachitatu ndizinthu zotsiriza za mano kuti ziwoneke pakamwa. Amakhala akuyenda pakati pa zaka 17 ndi 21.
Chifukwa cha msinkhu umenewu, iwo adadziwika kuti ndi "nzeru" mano. N'kutheka kuti dzina loyitanidwa liri ndi chochita ndi malingaliro kapena chikhulupiriro chakuti "ndi msinkhu umabwera nzeru."
