## What is Personal Greatness Index (PGI)?

How Does Personal Greatness Index works?


Current health and wellness app have traditionally been focused on physiological approach, Personal Greatest Index (“PGI”) is taking the different approach and studying the role of human body as brain fuel, to enable the thriving of all people – from a neuroscience approach.


For the BrianFuel Index, PGI is pioneering new generations of computational models of the biorhythms hierarchy system.


The goal is to bring these computation models "to life" by collecting biometric, lifestyle and mental well-being data so that a person’s neuro-cognitive model can change and adapt over time to reflect neuroscience based predictions like multitasking and rational decision making abilities.


BrainFuel index aims to weave insights from 7 daily lifestyle data, sleep, breakfast, lunch, dinner, cardio exercise, digestive system and daily summary, into brain performance mathematical models.


One of the goals of BrainFuel Index is to provide useful insights and predictions that are based on what happened in the past 72 hours, in terms of 3 main health pillars, hormonal, psychological and neurological science.


Is Personal Greatness Index effective?


Personal Greatness Index uses micro habit & selfie therapy (“MHST”), the most effective form of therapy to improve self care. Working with MHST does not require an in-person professional and therefore gives uers the power to do it in a guided and self-experimented way at their own time.

## Frequently asked questions about Personal Greatness Index (PGI)

### What is PGI's approach to health and wellness?

PGI takes a neuroscience approach, studying the brain as 'brain fuel' to enable thriving. It focuses on computational models of biorhythms and uses lifestyle and biometric data to adapt a user's neuro-cognitive model.

### How does PGI provide insights into cognitive condition?

PGI's unique algorithm provides an estimated cognitive condition based on lifestyle choices. It analyzes data from sources like Apple HealthKit for heart rate, sleep, and cardio, alongside mental well-being and digestive system data.

### What is micro habit & selfie therapy (MHST) in PGI?

MHST is presented as an effective form of therapy within PGI to improve self-care. It allows users to engage in guided self-experimentation at their own time without requiring an in-person professional.

### What kind of lifestyle data does PGI use?

PGI weaves insights from 7 daily lifestyle data points, including sleep, breakfast, lunch, dinner, cardio exercise, digestive system, and a daily summary, into its brain performance models.

### What are the main health pillars PGI focuses on?

PGI provides insights and predictions based on the past 72 hours, focusing on three main health pillars: hormonal, psychological, and neurological science.

### Does PGI integrate with Apple HealthKit?

Yes, PGI integrates with Apple HealthKit to gather data such as resting heart rate, cardio data, and sleep data, which are used to assess allostasis load, brain oxygen intake, and brain healing levels.
