Dr Wible who wrote the article on med students on medication (antidepressants and/or stimulants) did a TEDMED talk on "Why doctors kill themselves" http://www.idealmedicalcare.org/why-doctors-kill-themselves/ which refers to the problem with the medical system itself. If the healer is mentally ill (and most of them are), how can we expect the best medical care? The fact that med students take medication is just the tip of the iceberg.
