These high end escorts at best, have a good 10 years in them to make great money, assuming they don't get caught up in drugs and begin to look like shit before hitting 30.
Like Jelly Roll's wife, she was a high end escort, I saw some videos of her in her prime and she looked amazing. She is still relatively decent looking for her age, but definitely not pulling 2k/night any more, even though she never needs to work again.
