Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Zvidzidzo zvinoratidza kuti pane kuwirirana pakati pokuva muduku nokurarama kwenguva refu. Vanhu vane chimiro chiduku vanewo mukana wakakura wokuva neBP yakaderera uye vane mukana muduku wokubatwa nekenza. Yunivhesiti yeHawaii yakawana kuti <unk>gene yokurarama kwenguva refu<unk> FOXO3 inoderedza migumisiro yokukwegura inowanwa zvikuru muvanhu vane ukuru huduku hwomuviri. Kuva mupfupi kunoderedza njodzi yokushaya simba kwemuviri. Kana vanhu vakagara nhaka imwe chete uye vachigara pamwe chete, kakawanda kacho zvinoratidza kuti vari boka rimwe chete. Kusiyana kwakasiyana-siyana kwehurefu (kutsauka kweanenge 20% kubva paavhareji) mukati mevanhu vakadaro dzimwe nguva kunokonzerwa negigantism kana dwarfism, zvinova zvirwere zvinokonzerwa nemajini chaiwo kana kusagadzikana kwe endocrine. Kukura kwehurefu hwemunhu kunogona kushanda sechiratidzo chezvinhu zviviri zvakakosha zvehupfumi, kureva hutano hwakanaka uye hutano. Munharaunda dzine urombo kana hondo, zvinhu zvakatipoteredza zvakadai sokushaya zvokudya zvinovaka muviri kwenguva refu muvana kana kuti vachiri kuyaruka zvingakonzera kunonoka kukura uye/kana kuderera kunoshamisa kwechimiro chomunhu mukuru kunyange pasina chimwe chezvirwere izvi. Kumwe kutsvakurudza kunoratidza kuti kukwirira kwakakura kunobatanidza nokubudirira kukuru mukufambidzana uye kuwana muvarume, kunyange zvazvo kumwe kutsvakurudza kunoratidza kuti izvi hazvishandi kuvarume vasiri vachena. Kureba chinhu chinoratidzika kuti chakasiyana pabonde muvanhu. Imwe fundo yezvinoitika zvokuberekwa kwevanhu muBritain muzana ramakore rechi20 yakaratidza kuti nepo varume varefu vaiwanzobereka vana vakawanda kupfuura varume vashoma, vakadzi vari pasi porurefu hwepakati vaiita vana vakawanda kupfuura vakadzi varefu.  Mubvunzo: Chii chinokonzera kusiyana-siyana kweurefu?
