Those who come on top in their social and professional lives have higher stress hormone levels, a new study published in the journal Science reveals.
Researchers from the Princeton University carried out the study on 125 male baboons from five different social groups in Kenya. On testing the levels of glucocorticoid and testosterone from the droppings, the researchers found that both the hormones were higher among the leaders in the groups.
Lead researcher Laurence Gesquiere said that the findings were also applicable to humans since baboons are very similar to us both genetically and the type of complex social lives that they lead.
"An important insight from our study is that the top position in some animal - and possibly human - societies has unique costs and benefits associated with it, ones that may persist both when social orders experience some major perturbations as well as when they are stable", Gesquiere said.
