President Muhammadu Buhari is on visit to his home town Katsina. I am really impressed with what he is doing. Rarely do we see Nigerian president humbly do such. He is leading by example administering polio medication to some children in Katsina. It is a good thing for it is a big advert and campaign against polio which is affecting some part of Northern Nigeria. Nigeria is one of the few country remaining which are yet to eradicate polio completely.
