Thick vs. skinny body type

Disclaimer: I know both are beautiful and everyone's body is different.. I just want to have a discussion and get different opinions

I am posting this merely to spark a discussion about the whole skinny vs. thick body type debate. I can't stand how the media and men try to tell women what they should like.. I was recently told by my SO that I'm getting "thicker" (I've always been naturally skinny due to metabolism and just generally being active). Also I keep getting comments from my family about how i need to start working out again. And I don't know if I should be offended or happy about these reactions. Just to give a bit of info I am 5'2 and 125 pounds.

My question to all of you is should we care as long as we're healthy? What are your opinions?
