2019 Elections: Should We Really Not Vote For A Leader Above 70years Of Age? But Is There A Choice?

Let me start with a question? Has Nigeria ever had a better leader since handover to civilian government in 1999?
2019 is fast approaching and a new regime has to be elected into power. Many people support the idea of not voting for a leader over 70years of age. The idea erupted from the present administration.
Before Buhari came into power, many prophets prophesized that he was God-sent and would rescue Nigeria from the clutches of corrupt hands. We bought it all. Now after 2years plus, we hear the same prophets telling us that an old man cannot rule Nigeria and we shouldn't vote for him again in 2019. Looks like a merry-go-round to me. Some of them even said that he is already a dead man, a peep away from the grave (no insult to Mr. President, Sir).
I laugh at them. We don't need Prophets to tell us who to vote for. We have the power and initiative to vote for whoever we want. But look at it this way, how many presidential candidates are even below 65years of age in Nigeria? None! Truth is, Nigerians have no choice. We take what we are given. The politicians run this country and do not serve us. Rather, we serve them.
If someone like Atiku (at his age) is running for 2019 presidency, what hope do the "leaders of tomorrow" have in becoming a presidential candidate? Your opinions are greatly needed here.
