I believe it's wrong to decide which age is right to get married! Many of you, guys, said "it depends on the person him/herself" and that's true! The essence of marriage is the brain (understanding each other and the responsibility marriage requires). You can find some 19 years old male and he understands more than a 28 years old man!! Yes it's rare to see that, but it exists. We can't prevent that 19 youth to marry since we saw how responsible he is. The same thing goes for the females. Age was never a scale to measure the brain's ability. The public view and opinion is that the older the wiser, true but with exceptions.
I agree to let the people marry when thay are ready, no matter what age they are. Everyone knows the best for him/her, afterall.
