If it wasn't for christianity imposing the Dark Ages on Europe we might've cracked cancer a couple of centuries ago.
My positive contribution to future generations is not to prey, but to leave my house to cancer research. I'm guessing that's the best part of a century away, so in the meantime I contribute heavily to cancer research.
Cute and sends a message.
But one cant always fix terminal cancer. Thats when its time to pray or if you are an Atheist. Its time to die without hope.
