If 'The Fear' has taken over your whole body, then you probably will have no choice but to stay stuck to the sofa today.
And with a documentary like this coming up, you're not going to want to move anyway.
In his latest documentary which airs on Sunday night, Louis Theroux has said that it's one of the 'most difficult' he has made to date.
The documentary-maker visits California, one of six states in the US where the terminally ill have the right to end their own lives.
He investigates the moral and legal issues surrounding this situation, meeting people who have made the choice to die, but now need to decide when, as well as a group that helps people who do not fit the legal criteria.
Speaking to Radio Times, he said the doc 'Choosing Life' was an extremely hard one to film but he tries to separate his feelings from his work.
“I’ve seen quite a few upsetting situations. And I think sometimes I may lack a certain level of emotional self-knowledge.
"Occasionally I get surprised when emotions come at me unexpectedly. But, for the most part, I’m unscathed.
"It doesn’t traumatise me. I see something extraordinary, I’m part of a very powerful, upsetting scene in which someone is dying, or expressing a deep sense of mental anguish, and then I go home, put my kids to bed and kiss my wife.”
