The heart of the children is very soft and simple compare to that of the adult I can easily call it a virgin heart. That is why you can never see a baby having heart attack, they are always happy, they have no enemies, they see things the way God created them.
But in the process of growing up we begin to encounter a lot of challenges, a lot of battles, a lot of difficulties in our day to day activities, from there our heart gradually becomes heavy and loaded. That is why heart attack is rampant in the mids of elders but spread to tenegers nowadays due to early struggling for success. But notwithstanding it is said that what doesn't kill a man will always make him stronger.
