    Very calm. Knowledgeable. However, doesn't seem to really look at the individual. But it just might be how the system is set up.

    He was a fine physician, now he listens while inputing information into the computer. He no longer does a number of tests/checks he used to. He no longer does a hands on physical and most all complaints are given a referral. He has lost his compassion and his urge to be more than a information collector.
