Its not that easy to do both the shows.
And hosting is also not easy, they should follow the script and decide what to say and not to say and they should be there from starting to the end of the shoot.
Yes many of others did it before, but in that shows there are multiple important Characters/couples on whom the focus of the story can be shifted but here The story mainly focuses and the main leads and he needs ti be in every frame.
So its definately difficult for him,love him more for his dedication,hardwork
And many people like me watch nach only for him and chote and bade are usp of the show and i heard that their hosting is even bigger and better than last time.
All i can wish is that god bless him with good health.
Loved ur post:-)
