Our Brain
Our brain is divided into 2 parts - Left Brain & Right Brain.
Left brain controls right side of the body and vice-versa.
Science has proved that within same lobe, Left & Right brain do different specific roles. So, brain has 10 compartments - 5 left and 5 right. Each compartment has specific, pre-defined function.
Further, our brain has approx. 100 billion Neuron cells which are randomly divided in these 10 compartments. It is impossible that two persons have same neuron distribution.
One would love to do that compartment's work which have more neuron count. One will enjoy that work, will find it easy and will be their strength area.
One would hate to do work related to a compartment in which the neuron count is low. One will find it difficult to do and will be their weak area.
This neuron distribution affect the formation of fingerprints and can thus indicate one's abilities.
Brain Lobes & their functions

1. Inferior frontal lobe:
Emotions, reasoning, planning, movement, parts of speech, creativity, judgement, problem solving & planning.
2. Parietal lobe:
Kinesthetics, fine & gross motor skills, space discrimination, understanding & appreciation of space, Art and language capability.
3. Prefrontal lobe:
Executive functions, cognitive functions and personality.
4. Temporal lobe:
Hearing, memory, emotions, learning, Interpreting & processing auditory stimuli, language comprehension.
5. Occipital lobe:
Ability to recognize objects, responsible for visual functions.
