Unless you can prove otherwise, I have no qualms endorsing that pic from NMG, first as a parent of two teenagers girls, one in class 8 - going to form 1 and also another in class 7 - going on to class 8.
One thing though, whenever I attend parents day/ open day, and honestly, teachers and fellow students keep asking if indeed I am the Daddy, or an imposter, I look more of a brother than the father. Mimi ni zoea hayo.
Advise to younger people, start early. Wacheni ulevi mingi, keep fit and eat well and more importantly practice fidelity.
The youngsters whom you help change diapers for will soon be teenagers....by which time you may have developed a beer pot belly and a balding head. Not a pleasant sight, but it is there - today's lifestyle.
