Waa maxay ilmo-xannaaneeye, oo lebbis caynkaas ah sita oo kale ayay ku wareegaysaa, aniguna aniga qudhaydu waxa aan doonay ilmo ilaaliye. Nin qaan-gaar ahi wuu ogyahay nanniesyada ku habboon wiilkiisa. Middani waxay leedahay godadka oo dhan way shaqeeyaan waxayna u shaqeysaa si xirfad leh.
Inta ay marwadu jikada ku jirto, inanteedu dhib uma hayso in ay ninka wanaag u samayso oo ay u ogolaato in uu jagooyin kala duwan ku waso.
