Lipoti loyamba la vuto la kukhala kuntchito linabwera mu 1953, pamene wasayansi wina wa ku Scotland dzina lake Jerry Morris anasonyeza kuti anthu ogwira ntchito mokangalika, monga ma kondakitala a mabasi, savutika kudwala matenda a mtima kusiyana ndi madalaivala ongokhala.Anapeza kuti mosasamala kanthu za kukhala a gulu limodzi la anthu ndi kukhala ndi moyo wofanana, madalaivala anali ndi chiwopsezo cha mtima chokwera kwambiri kuposa ma kondakitala, ndipo amene poyamba anali pangozi yoŵirikiza kaŵiri ya kufa ndi nthenda ya mtima.
Katswiri wa matenda a Epidemiologist Peter Katzmarzyk akufotokoza chiphunzitso cha Morris.Si makondakitala okha amene amachita masewera olimbitsa thupi kwambiri zomwe zimawapangitsa kukhala athanzi, koma madalaivala omwe sachita.
gwero la vuto ndi loti mapulani a matupi athu adajambulidwa kalekale pasanakhale mipando yamaofesi.Tangoganizani makolo athu osaka nyama, omwe cholinga chawo chinali kuchotsa mphamvu zambiri kuchokera ku chilengedwe ndi mphamvu zochepa momwe zingathere.Ngati anthu oyambirira ankatha maola awiri akuthamangitsa chipmunk, mphamvu zomwe anapeza pamapeto pake sizinali zokwanira kugwiritsidwa ntchito panthawi yosaka.Kuti apereke chipukuta misozi, anthu anali anzeru ndi kupanga misampha.Physiology yathu idapangidwa kuti isunge mphamvu, ndipo ndiyothandiza kwambiri, ndipo matupi athu adapangidwa kuti azisunga mphamvu.Sitigwiritsa ntchito mphamvu zambiri monga momwe tinkachitira poyamba.Ndicho chifukwa chake timanenepa.
Metabolism yathu idapangidwira bwino makolo athu a Stone Age.Ayenera kupha nyama zawo (kapena ayifufuze) asanadye chakudya chamasana.Anthu amakono amangofunsa wothandizira wawo kupita ku holo kapena malo odyera othamanga kuti akakomane ndi munthu.Timachita zochepa, koma timapeza zambiri.Asayansi amagwiritsa ntchito "chiwerengero cha mphamvu zamagetsi" kuti ayese zopatsa mphamvu zomwe zimayamwa ndikuwotchedwa, ndipo akuti anthu amadya chakudya chochuluka ndi 50 peresenti pamene akudya 1 calorie lero.
Nthawi zambiri, ogwira ntchito m'maofesi sayenera kukhala nthawi yayitali, azidzuka nthawi zina kuti aziyenda ndikuchita masewera olimbitsa thupi, komanso kusankhampando waofesindi mapangidwe abwino a ergonomic, kuteteza lumbar msana.
