How often do your jeans last?

It is such a cringe question but one of my colleagues commented that my jeans look old and I should throw them out.

I bought them 7 years ago from Levi's and wear them almost everyday. Ofcourse, they are faded from the navy blue that they were to a more whitish blue and it is quite worn out. I thought it added to the appeal.

I mean I can throw them out right now( they only cost me 2.5k back then) but I wonder what is the lifecycle of jeans for most people here.
