Should you Buy Critical illness Policy?

Few days back Dr Naresh trehan, CMD, Medanta Medicity quoted in DNA that "India will become the world's capital of heart diseases by 2015". Nowadays, not only are lifestyle disorders becoming more common, but they are also affecting younger population. Hence, the population at risk shifts from 40+ to maybe 30+ or even younger. Already considered the diabetes capital of the world, India now appears headed towards becoming the lifestyle-related disease capital as well. Well, you will agree with the fact that health treatment costs are increasing day by day and along with that with our sedentary lifestyle, job and family pressures, unhealthy eating habits, no exercising etc. we are very much prone to many diseases. All the above calls for an adequate cover for life, health, accident and critical illness, so that our financial Life should not get hit due to any unforeseen event. One should be adequately insured so that he/she can devote the quality time to other goals and responsibilities. But yes, as this policy is only one time payment policy so those who has a good cash flow and can maintain or create a good corpus for medical emergencies, then they may avoid taking this policy.
