Please note that this point is very important: For Dr Pascal, being a doctor and a scientist imposes the need for two other elements which are essential to the quality of the operations that he performs every day: research and communication of knowledge. Without working in these 2 fields, doctors quickly become out of date, always performing the same techniques. Reflection and especially rigour and high-quality research are just as vital as practice for progression.
A doctor must learn something every day by taking a step back from the surgical procedure.
