When did the habit of listing down things or notes get started?  Well, God gave Moses the Ten Commandments. The Bible also recorded the 10 plagues that hit Egypt. There were 12 tribes of Israelites and there were also 12 disciples who accompanied Jesus Christ in His ministry.

When I was still a little boy, my mother used to make lists of the things she wanted to buy before going to the market.  When I started working, I made a list of things I will do in a day or within a week (I have to check one by one those I have accomplished).  Here are my nine rules to live longer.

1. Do not overeat. 

2. Eat well-balanced, reasonably adequate meals, including fresh fruits, vegetables, and dairy products. 

3. When tired, irritated, or nervous, eat sparingly. 

4. Eat at regular times. 

5. Avoid agitation and aggravation, particularly at mealtimes. 

6. Keep your blood pressure down. 

7. Learn to live with life as it is.  Be philosophical. 

8. Avoid excessive X-rays unless absolutely necessary. 

9. Exercise each day, even if only by walking.
