Answer by Raqib Zaman:
Sleep enough. Your body needs rest to function (for most individuals). I recommend instead to focus on diet to maintain high focus. Since the function of the body is highly dependent on the diet. I find Ginger tea occasionally to bring me back to speed, and Coconut as the staple in a diet for high metabolism => high cognitive function.
Trust the Coconuts ☺☻☺☻
It works for me.
PS> Stay away from oils that rancidity easily, namely PUFA (polyunsaturated fatty acid) oils. You can observe that when they rancidify, they harden as a chemical change vs. saturated fats that harden due to temperature. Some examples of PUFA oils are cottenseed, canola, sun & safflower, Soybean oil, and fish oil. (Yes, fish oil is bad for you. Didn't your nose warn you? I guess that's why they put fish oil in pills now. Cod Liver oil has beneficial properties if the vitamin A & D aren't taken out of it.
PSS> Obesity, Cancer, diabetes, cardiovascular diseases are all actually a result of these PUFA oils. Many people don't know this. And get this, Animal fat is mostly PUFA in composition because of the corn/soy diet farm animals are fed. So blaming Animal fats solely for their Saturated fat content is ignorant of other oil fractions in the Animal fat.
