Isihlahla setiye siyisitshalo esingapheli: sinomjikelezo ophelele wokuthuthuka empilweni yaso yonke kanye nomjikelezo wonyaka wokukhula nokuphumula unyaka wonke. Umjikelezo ngamunye wesihlahla setiye kufanele usikwe kusetshenziswa aumshini wokuthena. Umjikelezo ophelele wokuthuthuka uthuthukiswa ngesisekelo somjikelezo wonyaka wokuthuthukiswa. Umjikelezo wonyaka wokuthuthukiswa ukhawulelwe yisamba somjikelezo wokuthuthukiswa futhi uthuthuka ngokuvumelana nemithetho yentuthuko ephelele.

Ngokwezimpawu zokukhula kanye nokusetshenziswa kokukhiqiza kwezihlahla zetiye, izihlahla zetiye zivame ukuhlukaniswa zibe izinkathi zeminyaka emine yezinto eziphilayo, okuyisigaba sezithombo, isigaba sobusha, isigaba sabadala kanye nesigaba sokuthoma.

1.Isiteji sezithombo zesihlahla setiye

Ngokuvamile iqala kusukela ekuhlumeni kwembewu noma ekusindeni kwezithombo zokusika, ukuvela kwezithombo zetiye, kanye nokuphela kokuyeka ukukhula kokuqala. Isikhathi esivamile unyaka owodwa, futhi ukugxila kokuphatha phakathi nalesi sikhathi ukuqinisekisa ukutholakala kwamanzi, ukugcinwa komswakama, kanye nomthunzi.

2.Isihlahla setiye isigaba sentsha

Isikhathi esisuka ekupheleni kokukhula kokuqala (imvamisa ebusika) ukuya ekukhiqizweni okusemthethweni kwezihlahla zetiye sibizwa ngokuthi yinkathi yobusha, okuvamise ukuba yiminyaka emi-3 kuya kwemi-4. Ubude balesi sikhathi buhlobene eduze nezinga lokutshala nokuphatha kanye nezimo zemvelo. Isigaba sobusha sesihlahla setiye yisikhathi sepulasitiki enkulu kakhulu. Ekulimeni, kuyadingeka ukuthena nge-fixedtea prunerukuvimbela ukukhula okuya phezulu kwesiqu esikhulu, ukukhuthaza ukukhula kwamagatsha asemaceleni, ukuhlakulela amagatsha aqinile omgogodla, futhi kwakhiwe ukuma kwesihlahla esiminyene. Ngesikhathi esifanayo, inhlabathi iyadingeka ukuba ijule futhi ikhululeke ukuze uhlelo lwezimpande lusatshalaliswe lujule futhi lubanzi. Ungakhethi kakhulu amaqabunga etiye ngalesi sikhathi, ikakhulukazi eminyakeni emibili yokuqala yobuntwana. Zama ukugwema ukukha amaqabunga etiye.

3.Isihlahla setiye ubudala

Isikhathi somuntu omdala sisho inkathi kusukela lapho isihlahla setiye sifakwa ngokusemthethweni ekukhiqizweni kuya ngesikhathi silungiswa ngaso okokuqala. Ibizwa nangokuthi isikhathi somuntu omdala osemusha. Lesi sikhathi singahlala iminyaka engama-20 kuya kwengama-30. Ngalesi sikhathi, ukukhula kwesihlahla setiye kuba namandla kakhulu, futhi isivuno kanye nekhwalithi kusezingeni eliphezulu. Imisebenzi yokuphathwa kokulima ngalesi sikhathi ikakhulukazi ukwelula impilo yalesi sikhathi, ukuqinisa ukuphathwa kokuvundisa, ukusebenzisa izinhlobo ezahlukene zezitshalo.umshini wokusika ukushintsha ukwakhiwa kokukhanya kanye nokwakhiwa okujulile, ukuqoqa ubuso bomqhele, nokususa izifo nezinambuzane eziwumqhele. Amagatsha, amagatsha afile namagatsha abuthakathaka. Ezigabeni zokuqala zokukhula, okungukuthi, isigaba sokuqala sokukhiqiza, kufanele kuqashelwe ukuhlakulela umqhele wesihlahla ukuze ukhulise ngokushesha indawo yokukha.

4. Isikhathi sokuguga

Isikhathi kusukela ekuvuselelweni kokuqala kwemvelo kwezihlahla zetiye kuya ekufeni kwesitshalo. Isikhathi se-senescence yezihlahla zetiye ngokuvamile sithatha amashumi eminyaka, futhi singafinyelela eminyakeni eyikhulu. Izihlahla zetiye le-Senescent zisengakhiqiza amashumi eminyaka esivuno ngokuvuselelwa. Lapho isihlahla setiye sigugile kakhulu futhi isivuno namanje asikwazi ukunyuswa ngemva kokuninganaumshini wokusika ibhulashiizibuyekezo, isihlahla setiye kufanele sitshalwe kabusha ngesikhathi.
