Growing up, I learned that everyone around me was respectful and my parents continued and fostered respect to me, they taught me to respect ancestors and everyone regardless their age, by doing so it is believed that one will gain blessings and increase days of living.
Other belief as a pedi is that for a man to be a man and gain the title of a man must undergo a circumcision ritual that is performed in a nonclinical setting on the mountain or bush for a period of 5 weeks in winter seasons, otherwise your are not a man no matter your age unless you go there.
