You can overcome both problems by learning how to perform surgery on yourself. Of course, you have to remember that some operations are far too complicated for the beginner. Even quite gifted amateurs will have difficulty in coping with delicate neurosugical procedures.
Amputations can be pretty tricky too.
Before you do anything at all you must plan your operation. You may have a cool nerve, steady hands and an incisive mind but you wont get far without a few instruments. Planning is all important in surgery. There is nothing worse than getting to the end of an operation and discovering that you dont have anything with which to close the wound. You'll find that walk to the local sudery appliances shop twice as long when your having to hold the edges of a gaping wound together.
