Another thing to consider is the short life of modeling careers. Adriana's has been pretty long, but that's only because she is one of the top and she's probably going to be done in a few years anyway. She's truthfully past her peak anyway- she doesn't even model that much anymore other than Victoria's Secret/Maybelline and the occasional runway show. Most models are in the spotlight very briefly and then they're too old, too "fat," or their look isn't "in" anymore, and that's that. Some don't even get that. It's a difficult thing to make a living solely on your physical appearance, especially with the fickle nature of the fashion industry.
