 Seven years of education, and that's just education to get you into working in a different setting. And we can work in all different types of settings. The most common one when dealing with chronic problems is the outpatient orthopedic setting, which is what we focus on at Athletico. And after that, it's not just you're in the clinic and now treating, but we're often pursuing advanced certification, residency, fellowship training to really try and specialize and start trying to treat some of these more complicated problems, such as chronic pain.
