Today would have been my grandmother’s 99th birthday. She passed away in 2011, but I still struggle with the idea that she is no longer alive and I will never see her again. As an atheist, I do not have the luxury of the idea of being with her again once I die. There is no heaven. There is no hell. Who we are – our mind, consciousness, personality, and character – is a unique combination of chemicals and neurons, which disperse once we have died.
