Speaking from the location David said: "I don't know why everyone is so eager to see me give up doing what I am best at doing. I've no intentions of falling ill."
David says that after his health scare last year when he collapsed during an event organised by Shashi Ranjan, health is a priority.
"I am looking after myself. There is no point in killing myself over the workload. There was a time when I was shooting two films on adjacent sets and sometimes an average of three films a year. Now I've nothing to prove. Let my sons do all the work. Not that I am planning to retire."
Reacting to reports that his elder son Rohit had taken over the direction of "Main Tera Hero", which stars his younger son Varun, David said: "Rohit is here to meet his father and brother. We are a family.
"And if I need him to direct for me, I'd happily ask him. Right now I am hale and hearty and I am on location in between shots as we talk."
