If talking and walking is what it takes to be an actor, I guess all of us can be a part of the profession;)
Talking not only about KSG but TV actors in general. Esp those belonging to Indian TV.
They have horrific schedules, work almost 18 hrs a day, sometimes shoot for two days altogether. There is no fixed office timings like 9-5. It all depends on the TRP's and what the channel wants. For eg, if the channel wants to do a mahaepisode or a mahasangam, these guys have to oblige. So you have lots of news reports about this actor and that actress falling sick or fainting.
Atleast US tv shows run in seasons and sometimes give long breaks in between. Unlike our shows which run for years altogether!
No profession is easy in the world. I think we have to respect each other for what we are and the work that we do without dismissing it flippantly.
