Kalenjin generally have young leaders. The are a few disanours - who are 55-60s - and potbellied like Isaac Ruto - otherwise the young generations are generally fit - but you have somone like Elgeyo Marakwet governor Tolgos - who obese and short.
Otherwise majority of the leaders are in their 30s and 40s. They are led by Ruto at 54 - and this new post Moi generation that is big break from the past dynastic elite selected Moi crap.
In other news, refreshing to note that these Kalenjin leaders are not pot-bellied like the dynasties and gluttons from other parts of the country. UK high commissioner aptly described the latter as vomiting over their shoes.
