His schedule is disciplined — 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't it?," he says, adding, "He is very relaxed on the set. Until now, I have only heard about the 'live in the moment' attitude, but I got to see that in him. It was great working with him."
