From science blogger and noted atheist P.Z. Myers, I learned that it’s a good idea to not ignore chest pains; and an even better idea to listen to your doctor when she tells you in a VoiceOfDoom™ to get into the hospital right now!
Oh, yeah, and that godless people are a great-hearted bunch, on the whole. Pun gladly intended, of course. Don’t lose time in prayers, go donate blood instead if you can! (Thank you, Cuttlefish.) Another good idea is to give money to medical research. And what more poetical outcome than a science popularizer like PZ reaping the benefits of science when he needs it?
Don’t count on your hard disk too much, or prepare to pay $$$ to data-retrieving professionals.
