The recent general elections where some senators were re-elected after spending about 18 years in the National Assembly now makes the position looks like a retirement home to politician. The likes of senator Ike Ekweremadu, James Manager who has been a senator from as far back as 2003 and they both just got reelected to stay for another tenure is alarming.
There should be a stipulated retirement age because with age, the mind and brain function deteriorates. With a faulty mind and brain a lot of mistakes can happen, fresh ideas are no so easy to attain. Some would claim a secretary or an assistant can fulfil the senator's duties, but this is wrong because they were not the ones elected to do those jobs. Most of the times, fresh ideas brought to their table can be disregarded because of lack of understanding that sometimes comes with age.
If the senate can dictate tenures and retirement Age for public servants, they themselves shouldn't be left out because they are also public servants.
In Canada, their constitution was amended a retirement age of 75 for senators was made into law. Besides if there's an entry age of at least 35 years to be elected as a senator, why isn't there any stipulated retirement age?.
The retirement age for a teacher was recently amended to 65years of age or 35 years of service. That of a supreme court Justice and Judges in the lower court is 70years of age, military officers 62 years of age.
Interestingly, a majority of advanced countries practicing democracy has no term limit or retirement age for the legislative houses. Here in Nigeria this practice has to be put in check. Because Nigeria seems to be a peculiar country where people cling to power as if their life depends on it.
