These enzymes, called rennet, are secreted by mucous membranes that line the calf’s… »6/15/15 11:57am6/15/15 11:57am

The Surprising Connection Between George R.R. Martin And Frank Miller

Your Doctor Probably Has A DNR. Here's Why You Should Consider One, Too.

Most patients receiving end-of-life care want to avoid aggressive attempts to prolong their life, but medical culture and practices often contradict these wishes. Part of the problem is due to confusion surrounding do-not-resuscitate orders. Here’s what patients really need to know about the “no code.”
