The sons, males, may fall into different age set groups, starting from that listed (first born), which may depend on the age set then current at the coming of age of a son. For example, if your father was a Chuumo, he would have first born son circumcised into Korongoro (firstborn), Kipkooimet, Kapleelaach, and Kipnyigeei, but daughters fall into only one age set, Masinya. 2. For women, they have their NATURAL (Born) age set and their ADOPTED (married-oboo) age set the age set of the man she marries or gets married to is the adopted a/oboo, e.g., Kipkooimet, and hence all wives of this age set are (bookinei, pookinei, or mechei, depending on the tribes you come from) to all the male age sets; however, the women have their own natural/born age sets. 3. In Kalenjin only three tribes have seven agesets that's Kipsigis (no Kipkoimet), Nandi (no Korongoro), and Tugen (no Maina). 4. For example, a Kipkooimet can't marry or shake hands with a Chelemei his age-set's daughter but touches only the head, uttering a universal greeting phrase that is likewise responded to by the greeted—applicable only to circumcised ones!
