<p> Tamil star Karthi is totally impressed with our Greekuveerudu of Tollywood Nagarjuna. Karthi has shared some interesting work experiences with media.</p> <p> &nbsp;</p> <p> &quot;I observed him during the film&#39;s shoot and found him to be a meticulous worker. He is very regular with his workouts and maintains a strict diet. His schedule is disciplined &mdash; he goes to bed early and wakes up early. But then, his positive attitude is also a reason he is physically fit. A happy mind means a healthy body, isn&#39;t it? He is very relaxed on the set. Until now, I have only heard about the &#39;live in the moment&#39; attitude, but I got to see that in him. It was great working with him, &quot; says Karthi.</p> <p> &nbsp;</p> <p> Nag is playing the role of a quadriplegic patient and Karthi as his care taker.
