Biorhythm is some sort of a measure of a person's intellectual, emotional, physical, intuitions, aesthetics and other moods at a given date. This is determined by just giving the data of a person's birth date. It is displayed best in curve graph showing the peaks and lows of those conditions and moods.

I recall a couple of decades ago my brother telling me about this. Then, there were still no computers to find out more about it. I think astrologists had some sort of formulas and equations to properly graph them. If I remember right then, you will need a graphing paper where you would make a scale from the middle of the graph. Upward will be a positive scale, and down from the middle, represents negative side of it. From the data provided by those who compute a person's biorhythm, points on the scale will be marked and the curves drawn. This could be done on a daily basis, or for a given period of time, weeks before and weeks after.

Recently, I was trying to make a search of biorhythm online but all I could find were sites that required subscription to provide you a complete graph that you request. Fortunately, I am a member of a social site, Facebook. This social site has so many applications that come along. Sometimes you feel like tiring out of using them because many do not have real good use. Most are just for entertainment online. A couple of weeks ago a friend sent an invitation for the Biotrend application. To my surprise and elation, it was exactly what I was looking for. A free source for biorhythm! What's more nice with it is, you are provided with both your Western and Chinese zodiac signs, which I think, are the basis for the biorhythm graph projections. After typing in my birth date, the application quickly showed a graph of my biorhythm for the past two weeks and the next two weeks. The date I did the biorhythm is included in the projection. Two types of graphs will actually show, one bar graph and the other is the curve. My biorhythm for those days was very accurate. My emotions and physical conditions were really down and low. In relation to the past week's events, there were really factors that affected my emotions and physical condition. We encountered a serious family problem. From that time on, I had frequented almost daily my Facebook site to check on my overall condition and mood. In that way, I was able to adjust to them properly, knowing in what state I am in.
