Mikangano za zaka zomwe zimawerengedwa kuti ndizoyenera ukwati, zisathe. Ku Europe ndi United States, akwati ndi mkwati ali "akakalamba": Kuchulukitsa ubale mwa anthu kuyambira 35 ndi kupitirira. Amaganiziridwa kuti amakhulupirira kuti kupanga banja kuyenera kukhwima komanso mwamakhalidwe komanso mwandalama. M'dziko lathuli, ambiri amavutika kukondwerera chikondwerero cha 30, popanda kukhala ndi mkazi wamba. Ngakhale zili choncho, ofufuza aku Britain adaganiza zodziwa kuti ndibwino bwanji ukwati chifukwa cha sayansi. Mtolankhani waku Brian wachikhristu komanso wasayansi wa CERCIV Grifrith posachedwapa adatulutsa buku lomwe limatchedwa "Lamulo la 37%" likuwonekera. Ndizakuti, malinga ndi olemba, zingathandize aliyense kuchita chilichonse pa nthawi.
Chifukwa chake, kodi ali ndi zaka ziti zofunika kupita ku ofesi ya registry, malinga ndi Christith ndi Griffiths? Zaka 26. Zowona, chiwerengerochi ndichofunikira - chimawerengeredwa malinga ndi algorithm otsatirawa: Anthu amayamba kukwatiwa kapena ukwati, anthu amayamba kuganiza (malingana ndi olemba) zaka 18 mpaka 40. Ndipo nthawi yabwino yomaliza ukwati ndi 37% ya nthawi yonseyi. Nthawi yomweyo, Christith ndi Grifffiths adawona kuti pali kusiyana zaka 22 (kuyambira zaka 18 mpaka 40) minus 17%. Ngati mutayamba kuganiza za banja lomwe silinakhale ndi zaka 18, ndipo pambuyo pake, kenako "m'badwo wanu" waukwati, motsatana, amasuntha. Ndipo Griffiths ali ndi chidaliro kuti kupeza mnzake pa moyo patatha zaka 26, koma chaka chilichonse mwayi wolenga banja losangalala kumachepetsedwa.
