Asked by: Cindy Peabody. The ocean reflects the color of the sky, but even on cloudless days the color of the ocean is not a consistent blue. Phytoplankton, microscopic plant life that floats freely in the lighted surface waters, may alter the color of the water.
How long does it take to digest food â from the time you eat it to the time you excrete it? Answers from Michael F. Picco, M.D. Digestion time varies between individuals and between men and women. After you eat, it takes about  six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food.

I agree that there is no strict formula for this, since it also depends on what you eat and how you intend to expend that energy.From my experience if I eat a large meal which is heavy in carbohydrates I see my best performance with a high intensity exercise 6 to 8 hours later. agree that there is no strict formula for this, since it also depends on what you eat and how you intend to expend that energy.
