Look at a chicken’s life. From the beginning of its life to about the time it reaches 40 days, it’s fed everyday. Every single feeding will firm up the bird’s belief that it is natural rule of life to be fed everyday by friendly members of human race. And then one day, something unexpected happens, which revises its entire belief system. On 40th day (I came to know that is the best time to kill it for optimum tenderness), it reaches the maximum safety, when actually the risk is the highest!
