Do they test people for reality shows?

Question

In the case like Big Brother, where you're living with other people, do they test the houseguest, for any serious disease's. If not, I think they should.

Answer 1

Yes you go through an extensive workout. They test everything about you, from heart problems to food allergies. The last thing these networks needed is someone dying on their show. Shows like fear factor won't even look at you if you have asthma

Answer 2

They probably do. I know people have to take a physical for survivor.

Answer 3

no
