G. D. Birla has noted down some interesting facts about the historic week of 'Quit India' movement that Gandhi spent in Bombay. Birla remarked to Gandhi that why he is taking very little food. Gandhi replied, "Bombay has plenty of ozone in the air, and the metabolism is so low that one does not need to much of food here. If I take full meals, I shall fall ill. But there is another reason. My mind is more busy these days than ever before. You cannot think to much and yet eat much. It is safer to keep light." Birla writes, "When in Bombay, he (Gandhi) does not go out to public places for his walk. If he did, he would be mobbed by the admiring public. In Birla House, we have a small patch of lawn encircled by a paved pathway. In the circular track, Gandhiji takes walks of desired length. But in order to avoid walking in the same direction, Gandhi spends the first half walking clockwise and the second half in the reverse direction. Gandhiji is so fastidious even about these small things that while he may be discussing the most serious problem, after he has walked half his time in one direction, he takes right about turn and starts the walk in reverse direction. This ensures balanced exercise to the body."
