Are these tasks real?

Now some of the tasks can be done by anyone (hair coloring, hair cutting, etc). Some of the tasks look difficult but are they real -

1. Two hours lying in cowdung - it it was real cowdung, the contestant should be real sick by now with all bacteria, viruses, etc. Looked more like spinach saag with fake smell. Just like the task with fake snake, scorpion, etc.
2. Same thing with electric shock. Anyone would be dumb if the producers would allow shocks that would kill/hurt badly someone. The shock must be very low and generally acceptable for medical treatment. On the other hand, the contestant was dumb to speaking numbers so slowly. I should not take someone more than 20 seconds to speak up to 50.

You guys agree?
