Managed to read up to chapter 6 from Gary Klein’s book “Sources of Power: How people make decision” . He’s doing naturalistic decision making research, typically involving time pressure, high stakes, experience, inadequate information, ill-defined goals, poorly defined procedures, cue learning, context, and team coordination. He proposed “Recognition-primed decision model”, where decision makers experience situation in a changing context, recognize it, develop mental simulation and implement course of action… Still need additional round of readings to better grasp it.
Anyway, noted this website from my colleague Nutrition Data if you’re worried about calories intake 
Good site for health conscious people ( I can’t seem to find “jambu air” there. But I found that it is actually called “Water apple” here)
