Humans are made up of two parts. The two parts are 1) the visible human body which is perishable and therefore mortal and 2) the invisible human being which is imperishable and therefore immortal.
Human birth materializes when the invisible imperishable immortal human being enters or joins with the visible perishable mortal human body.
In contrast human death occurs when the invisible imperishable immortal human being departs or is disjointed from the visible perishable mortal human body.
Referring to humans as human beings is misleading. Human being is without the visible physical human body. Human body is without the invisible non-physical human being.
It is only when the human being is with the human body and similarly when the human body is with the human being, we are presented with humans.
Human body without human being is a corpse. And human being without human body is a preta.
Therefore, we need to use either the term human to refer to one with human body plus human being or we need to coin a new word indicative of the combination of both human body and human being, something like for example, human boding which refers neither exclusively to human body nor to exclusively human being.
Doctors’ and Nutritionists’ help and guidance can reach only up to the visible perishable mortal human body growing inside the womb during pregnancy and growing outside the womb after the delivery.
The visible perishable mortal human body is just like a vehicle and the invisible imperishable immortal human being is like the owner or driver of the vehicle operating the body with one’s own preferences, prejudices, choices and decisions to fulfil one’s own desires, aims, and objectives.
Life span of an individual human is measured as the time between the birth and death of the visible perishable mortal human body.
But the value, significance, relevance, achievement, success, usefulness, meaningfulness, and character of an individual human are all measured by what all the individual human’s human being does with its human body during its stay with the perishable mortal human body.
Couples happen to be the doors through which humans come into this world with their perishable mortal human bodies and imperishable immortal human beings combined or joined together.
