There is a shortage of neurosurgeons in the United States. People aren't as excited about getting into the brain biz as you might think, considering the hefty pay scale. In fact, the shortage is expected to continue for at least the next 20 years, so that gives you time to get through medical school and a residency program, and strap on a pair of latex gloves. One of the reasons that there are so few brain surgeons is the high rate of retirement. Surgeons retire early due to high malpractice costs and stress. The good ones make enough money by the time they're 50-55 that they can put aside the scalpel and relax, at long last. Now they can spend their time on a golf course, hacking up the rough rather than delicate human organs.
