Had no idea people upgrade their rings?

Okay, so maybe I've been living under a rock, but I really didn't know this until a couple of months ago and now I see it everywhere.
    A couple of my friends and I went out. Two of them are engaged: one for a year and one for about 6 months. Both of them have upgraded their engagements rings... I, on the other hand, have been married for 4 years and still have my original engagement ring and wedding band... They were all shocked and awkwardly disgusted that I still have my same rings lol! 
   I just feel like my original ring has so many memories tied to it... I just didn't know people got different rings like that. Then again I'm really not a flashy jewelry person.
