Wrinkles are a well known "cost" of being thin after a certain age. I've heard it said that an older woman may have to choose between her face and her hips. I'm sure we've all seen many very thin older women (over 60) whose faces look--I don't know--the word tragic comes to mind? It helps with wrinkles if you get plenty of essential fats in supplement form, as well as eating the fats necessary to LCing.
