Unfortunately, I was disillusioned in my past by both smoke and prayer, but I nonetheless feel I must say something. You have my support as well in hoping your sister in law will never die of cancer, and my congratulations for her conquering cancer. My grandpa died of cancer, there was nothing they could do about it, it had metasticized throughout his body, he could not even move, there was so much pain and suffering in him. He just...faded away. Nothing is more sobering than joking with your loved one day, then seeing his corpse the next with your own two eyes. Gotta wake up and enjoy your life, 'cause you never know when something horrific will sit you out of the game, and there is no coming back, unless I am wonderfully wrong and the afterlife does indeed exist. Anyway, I did not mean to rhapsodize about my suffering. Here's to hoping you never need worry about out of control cellular mutations again. Peace.
