My biggest fear

I've never feared from darkness or spiders, I may feel a little disgusting from blood or bugs; but it is not fear or phobia yet.

I only fear death and cancer.
I only need to be remembered for ever, even after I'm gone. I'm living my whole life just to be remembered always and forever.
And about cancer, I do fear cancer. It is something scary with no reasons and no well-known cure yet. For me it is a beast I always pray God to keep it away from me and my beloved people.

Those are the 2 biggest fears I have. Death and Cancer!
