I've said before and will no doubt continue saying it for a long time, few doctors are gifted at diagnosis, and diagnostic skills are not well-taught at med schools these days. Lab testing has taken the place of actually listening carefully, asking probing questions, and laying hands on the place that hurts to see exactly HOW it hurts.

Not that modern medicine doesn't beat the pants off the generality of medicine a century ago, but in the process some very simple, useful skills have been tossed out with the bathwater.
