what advantages does a person have in being a neurosurgeon? and how does this career negatively affect their quality of life?

I am not a neurosurgeon, so I cannot answer your question exactly. However, I have a daughter with Epilepsy, suffering from grand-mall seizures every week. We tried many medications. She also had a simulator implanted by a neurosurgeon. However, nothing works yet. We see great demand for more and greater neurosurgeon to change people's lives.
