Do actors feel pressured in Farah Khan's presence?

Here's an interesting episode on the sets of 'Main Hoon Na'. Actor Suneil Shetty suddenly started feeling dizzy and was diagnosed with low blood pressure, director Farah Khan asked him to take adequate rest, before he could be ready for the shoot. Although everything went on well, later, the question on everyone's minds was, why do things go wrong when Farah Khan is on the sets? The reason for the question stemmed from the fact, that recently, Shahrukh developed a bad back, in Farah's presence. With the superstitious Bollywood, hope these incidents do not take an ugly turn for Farah.
