I read every comment posted to this blog. I reserve the right to delete comments or close topics for any reason at any time. I welcome and encourage dissenting views, but profanity and personal attacks will not be tolerated.

I recognize this represents a change from the past, more free-wheeling days of the blog where comments were rarely deleted.

Kevin, M.D. receives a significant number of comments daily, and moderating comments is pretty much at the bottom of my priority list. So if I miss a few, I apologize in advance. Please do not email me requesting specific comments to be deleted. Just move on.

Thank you for your continuing readership and support.
