Pick your poison. Which one scares you the most? Or should I say....which one do you focus on the most, obsess about the most, and RESEARCH the most. I guess my biggest one will always be cancer. I was already scared of brain tumors at the age of 12. And now I seem to be totally focused on any type of oral cancer - constantly looking in my mouth with a flashlight (which is forbidden, but I keep finding flashlights and doing it anyway.) And if one side of my mouth doesn't exactly match the other side....WATCH OUT!
