I considered watching Farrah Fawcett's documentary concerning her battle with cancer.
My mother was recently diagnosed with cancer (albeit at the very early stages) and I thought watching the documentary might help prepare me for what could happen in the future.
But as my roommate told me nothing can prepare you for such an eventuality.
I also would rather remember Farrah Fawcett at the height of her powers, not awaiting entry into death's door.
So I decided not to watch.
