Age difference of a married couple.

Hi everyone... Hope all of you are fine. All of us are well known about the age gaps of a married couple. Some couple give importance to it and some just ignore it. I am not so interested to think a lot about the age gap. In love marriage, it is nothing at all but in case of arranged marriage, some people consider it. They wish to have a certain age gape between the two. So what about you? Do you think that age gap of a married couple is worth to think? or it is necessary to have a age gape? What is/was the gape between you and your partner? Please share.
