Umbiko wokuqala ophathelene nenkinga yokuhlala emsebenzini wavela ngo-1953, lapho usosayensi waseScotland uJerry Morris ebonisa ukuthi izisebenzi ezikhuthele, njengabaqhubi bamabhasi, mancane amathuba okuba ziphathwe isifo senhliziyo kunabashayeli abangazithinti.Wathola ukuthi naphezu kokuba bevela esigabeni esisodwa senhlalo futhi bephila ngendlela efanayo, abashayeli babenezinga eliphakeme kakhulu lokuhlaselwa yisifo senhliziyo kunamakhondaktha, okungenzeka ukuthi abangaphambili babulawa isifo senhliziyo ngokuphindwe kabili.
Isazi sezifo eziwumshayabhuqe uPeter Katzmarzyk sichaza umbono kaMorris.Akubona ama-conductor kuphela abavivinya umzimba ngokweqile okwenza babe nempilo, kodwa nabashayeli abakwenzi.
Umsuka wenkinga ukuthi ipulani yemizimba yethu yadwetshwa kudala ngaphambi kokuthi kube nezihlalo zamahhovisi.Cabanga ngokhokho bethu abazingeli-abaqoqi, ababeshukumiseleka ukuba bakhiphe amandla amaningi endaweni ezungezile ngangokunokwenzeka ngamandla amancane ngangokunokwenzeka.Uma abantu bokuqala bechitha amahora amabili bejaha i-chipmunk, amandla abawathola ekugcineni ayenganele ukuthi asetshenziswe ngesikhathi sokuzingela.Ukuze kunxeshezelwe, abantu bahlakaniphe futhi benza izicupho.I-physiology yethu yakhelwe ukonga amandla, futhi isebenza kahle kakhulu, futhi imizimba yethu yakhelwe ukonga amandla.Asiwasebenzisi amandla amaningi njengakuqala.Yingakho sikhuluphala.
Imetabolism yethu yenzelwe okhokho bethu be-Stone Age.Kudingeka bacuphe futhi babulale inyamazane yabo (noma okungenani bayifune) ngaphambi kokuba bathole ukudla kwabo kwasemini.Abantu besimanje bavele bacele umsizi wabo ukuthi aye ehholo noma endaweni yokudlela yokudla okusheshayo ukuze ahlangane nothile.Senza okuncane, kodwa sithola okwengeziwe.Ososayensi basebenzisa "isilinganiso sokusebenza kahle kwamandla" ukukala amakhalori amuncwa futhi ashisiwe, futhi kulinganiselwa ukuthi abantu badla ukudla okungamaphesenti angu-50 kuyilapho bedla ikhalori elilodwa namuhla.
Ngokuvamile, izisebenzi zasehhovisi akufanele zihlale isikhathi eside, kufanele zivuke ngezinye izikhathi zihambe futhi zenze ukuzivocavoca, futhi zikhetheisihlalo sehhovisingomklamo omuhle we-ergonomic, ukuvikela umgogodla wakho we-lumbar.
