Ngokuqhelekileyo kukholelwa ukuba ukusela ngobungcathu kulungile kwimpilo yomzimba; olu luvo luvela kuhlolisiso lwamashumi amathathu eminyaka adluleyo, olwabonisa ukuba abantu abaselayo ngokulinganiselweyo badla ngokusela kakhulu kunabantu abaselayo kakhulu okanye abangaziseliyo utywala. Usempilweni kwaye akunakufane ufe ngaphambi kwexesha.

Ukuba oku kuyinyani, ke mna (umbhali wokuqala) ndonwabe kakhulu. Xa uphononongo lwethu lwamva nje lucele umngeni kule mbono ingasentla, abaphandi bafumanise ukuba, xa kuthelekiswa nokusela kakhulu okanye abangaseliyo, abaselayo abalinganiselayo basempilweni kakhulu, kodwa kwangaxeshanye bazizityebi. Xa silawula ubutyebi Xa kufikwa kwimpembelelo, izibonelelo zempilo zotywala ngokuqinisekileyo ziya kuncitshiswa kakhulu kwabasetyhini abaneminyaka engama-50 nangaphezulu, kunye neenzuzo zempilo zokusela okuphakathi phakathi kwamadoda aneminyaka efanayo ziphantse zingabikho.

Izifundo ezilinganiselweyo zibonise ukuba ukusela ngokulinganayo kuhambelana ngokuthe ngqo nokusebenza kakuhle kwempilo kubantu abadala abaneminyaka engama-55 ukuya kwi-65. Nangona kunjalo, ezi zifundo azizange zithathele ingqalelo into enkulu echaphazela impilo yomzimba kunye nokusetyenziswa kotywala. Bubutyebi (ubutyebi). Ukuze bawuphonononge nzulu lo mbandela, abaphandi baye baphonononga ukuba ngaba kungenxa yokusela ngobungcathu okubangela ukuba abantu abadala babe sempilweni, okanye ngaba bubutyebi babantu abadala obunokukwazi ukuphila ubomi obusempilweni.
