Does age matter in relationships?

According to my friends' around me and my experience, I think age really de matter in realationship. Because during the different age, the education they received are different, and they experienced the different current events, also they were in the different science and technology period, they face the different temptation, and even they text the different lifestyle, so this becomes the generation gap. And also when two people in different ages, when they face each other, because of their age, they would feel unnatural with each one, I think this is also the ethics works. I also have an idea that the reason age works in realationship is that they have no the same topic. So I think age does a lot in realationships.
