I'm surprised that the supermodels are supposed to suffer from short careers.
One could write a list of those still working and making more money than I could dream about. Maybe two or three decads at several million bucks per year ain't so bad.
The problem, if there is one, is that almost every model today who has a modicum of success is called a super, so the marque is devalued. But the real ones keep right on truckin'.
