Does the love and excitement of marriage die away after a certain time?

No I am not having mariage issues, nor am I married. I was just wondering if after you hve been married for a year, or however long if the love and “excitement” goes away?
I am wondering this because I have been in stores before and seen a 30 year old couple bickering and saying I hate you. Then yet I’ll see a 60 year old couple practically making out in the soap department.
Does the excitement die and then come back? Or do some people just have a better marriage then others do?
