The age at which a man is suppose to get married in my opinion has to do with personal decision. Marriage isn't like everyday relationships, it comes with a lot responsibilities. Hence, i fell It is only right for a man to decide on marriage when he knows his mentally ready or focused to take on such commitment. Other factors like having a stable and good living condition for starting a family also plays a vital role in the decision to get married. This will mean that age really doesn't matter when it relates to the explanation above.
Some people choose to get married for the sake of having a life partner, while the majority get married in order to start a family and raise kids. Drawing from this angle and the later reason, I would say that age has to be put into consideration too.
We probably all know what hormones are and their significance in our body system. They are mostly responsible for producing essential chemical substances in the body that controls and regulate activities of certain cells and organs. This simply means that both male and female hormones play a vital role in the activities of every day life including the process of reproduction. There's this health quote which says that hormones do not decline because we age, rather we age because hormones begin to decline.
From the perspective of health and the roles hormones play in our body system as explained above, it will be wise for a man to get married before the age of 40. This is because science has proven facts that most men begin to experience decline in hormone as early as age 30. Decline in hormone will mean loses in every major role hormones play in our body. Hence, In a bid to have a healthy marriage and increase chances of starting a family while being able to physical care for them, it's recommended a man to get married before he starts experiencing any form of hormonal decline.
