Camerounians, Ivoriens, Senegalese etc are taller, bigger and more masculine than Nigerian men who are not generally tall. Why?. It's only Hausas that tried a little bit to match these countries in height but not physique, others are generally short and round.
Is it our food or what else in our culture that is responsible for our small genes?. Can we reverse the small genes by intermarrying with these giant Africans?
