"Age is just a number" has been a very popular slang, meaning in relationships, especially marriage, the age of the couples don't mean anything as far as there's love and agreement.
Well on this topic, I think we all have different views to it and all our views should be respected, we're all different beings with different perspective to things, so I think it's a personal thing and everyone is entitled to make their choice as far as the couples are in one accord. Moreover, my take on this is that as a man I can't marry someone that's older than me. I don't believe in age is just a number in marriage, if it's friendship I can cope to be friends with anyone that's way older than me or someone that I'm way older than, but in marriage, I can't just cope.
If you're saying age is just a number in marriage, can you marry someone that's thirty or forty years older or younger than you? I know some people will say that's too much, but remember you said it's just a number. If your answer is no, don't join them to say age is just a number, only those that can cope with this kind of gap in age should say age is just a number. To say the fact many people saying age is just a number can't practice what they're saying, most people are just saying it. Anyways, before some people will come for my head lol, I must say again that love knows no bounds, we should be free to love anyone we feel like loving or getting married to but then again remember you can't cheat nature.
Are you ready to cope with the real life issues behind it? You and your partner can be fine with it, what about your family? trust me your family also has their part to play in your marriage, that's just it, you can't sideline them totally. Your partner will enjoy more, if they're in support of your marriage, if they love your wife or husband, they can go to any length to support him or her and vice versa. So before you also decide that you'll settle for someone that's way older or younger than you, even though you're cool with it, what about your family. Trust me marriage is not all about you, your partner also needs the support, love, care and companion of your family.
Can you also cope with the drama from your friend's and all of that, my dear brother and sister, your mental health is important, a lot of factors needs to be considered before making conclusion.
Again, lets do some Maths, lets say you're 30 years and you marry someone that's thirty years older, meaning your partner is already at age 60, how long will you enjoy your marriage, in a case where the woman is the eldest, what's the chance of a sixty year old woman giving birth to a child, and if it's a man, how active did you think you'll be able to enjoy your man in bed as you ought to, it sounds someone but that's the truth, we're not stones and somehow our body will request for this things.
In conclusion, if you're able to deal with all of this factors, whereby you, your partner and every other important persons reached a concrete agreement and a high level of maturity, congratulations but if not just go for someone that you'll be able to cope with, living happily and peacefully together.
