Need help with brain surgery? I should begin by reading the second edition of my new Wiley text, Common Errors in Brain Surgery (and How to Avoid Them). P.S. Don't worry too much about preventive measures or even planning the details of the surgery. Any competent surgeon can help you clean up the mess afterwards and if the first one won't, there's always another more helpful fellow down the hall. P.S. If you can’t find a brain surgeon who can help you—they can be a bit stuffy sometimes, consult a helpful gynecologist or proctologist with an interest in the area.
