When you go on a rollercoaster ride, it looks scary but yet, knowing that you got your safety harness on you, you are ok with going through with. Like jumping out of a plane, as long as you have your parachute that works, you are ok with it.

wuhan virus, we don't have a vaccine or cure so until we do, we are fear of the X factor or the unknown.
No, this wuhan virus is not deadly to me because I am healthy enough but still, that doesn't mean I will challenge it and say come here and enter my azz hole, I'm ready for you.
