You couldn't have said it any better, age is just something we use to keep track of time. Its like the concept of numbers and years.
Maturity is not a function of age. If it was, my country would not be as backward as it is. I mean, my president is over 70. For a man his age, he shohld be considered mature with the knowledge to take a country forward.
But naa, he doesn't know shiit. Age is still just a number. If you live by the ideals you share on your post, then you would make a good dad :)
Living a life of simplicity doesn't leave room for a lot of BS.
