We have a responsibility to take care of this body and mind. What do we do to take care of it? Ever thought of it? We buy a car don't we service it regularly so that it doesn't break down when we go on a trip. If we own a car for 10 years, how many times would we service our car? Maybe more than 15 times at least? What happens if we don't? Now how many times we serviced or did maintenance of our body? From the time we were born until now we could have eaten all kinds of food, that may include good healthy food or bad, unhealthy food, chemical preservative, junk food, fast food, etc.
