Kaŵirikaŵiri amakhulupirira kuti kumwa mopambanitsa kuli kwabwino kwa thanzi la thupi; maganizo amenewa akuchokera ku kafukufuku wazaka 30 zapitazi, wosonyeza kuti anthu amene amamwa mowa mwauchidakwa amakonda kumwa kwambiri kuposa amene amamwa mopitirira muyeso kapena amene samamwa. Athanzi komanso osafa msanga.

Ngati izi ndi zoona, ndiye ine (mlembi woyamba) ndine wokondwa kwambiri. Pamene kafukufuku wathu waposachedwapa anatsutsa malingaliro omwe ali pamwambawa, ofufuzawo adapeza kuti, poyerekeza ndi kumwa mowa kwambiri kapena osamwa, oledzera kwambiri amakhaladi athanzi, koma nthawi yomweyo amakhalanso olemera. Tikamalamulira chuma Pankhani ya zotsatira zake, ubwino wathanzi wa mowa mwachiwonekere udzachepetsedwa kwambiri mwa amayi a zaka zapakati pa 50 ndi kupitirira, ndipo ubwino wa thanzi la kumwa mowa mwauchidakwa pakati pa amuna a msinkhu womwewo uli pafupi kulibe.

Kafukufuku wochepa wasonyeza kuti kumwa mowa mopitirira muyeso kumakhudzana mwachindunji ndi thanzi labwino kwa okalamba azaka zapakati pa 55 mpaka 65. Komabe, maphunzirowa sanaganizirepo chinthu chachikulu chomwe chimakhudza thanzi la thupi ndi kumwa mowa. Ndi chuma (chuma). Pofuna kuphunzira mozama nkhaniyi, ochita kafukufuku afufuza ngati n’chifukwa cha kumwa mowa mopitirira muyeso n’kumene anthu okalamba amakhala athanzi, kapena ngati ndi chuma cha okalamba chimene chingathe kukhala ndi moyo wathanzi.
