Hey snare!
great selection of books - I've read all of them except the one by Krauss, but I enjoy watching him on youtube.
congrats on becoming a doctor and being at peace with yourself and becoming an atheist. It's a wonderful, logical, and deeply meaningful way of life and I couldn't be happier with my own path as well.
Thanks for sharing your good-bye note and best of luck on your journey of helping people in the real world.
