Cancer

Imagine you're 40 years old, smoking, living perfectly fine except for a chronic cough for few months..
You visit the doctor complaining of the cough and he decides to do a xray.
It showed a large tumor..
He refers you to the hospital for further investigations and you're told it's late stage..
Would you rather not know and continue living the almost perfectly normal life?
