Bodies decompose quickly unless they are embalmed
Do we live on after death? If so, where? Is there a heaven? What is heaven like? What happens to my body? What happens to my soul?
They are the greatest of all of life’s imponderables which have been tackled, with varying degrees of success by science, art and religion.
Here we look at the latest thinking in all these areas…
Medically speaking, death happens in two stages. The first, clinical death, lasts for four to six minutes from the moment a person stops breathing and the heart stops pumping blood.
During this stage, organs remain alive and there may be enough oxygen in the brain that no permanent damage occurs.
The second stage of dying, biological death, is the process by which the body’s organs shut down and cells begin to degenerate.
Doctors are often able to halt this process by cooling the body below its normal temperature, allowing them to revive patients before brain damage sets in.
After 12 hours, skin loses its colour and blood pools at the lowest point of the body, causing red and purple bruising.
Before this, rigor mortis sets in, making the body stiff and rigid. This is caused by calcium leaking into the muscle cells, which binds to protein and causes them to contract.
Scientists have worked out how our bodies decompose after we die
Unless the body is embalmed, it will start decomposing as soon as blood stops flowing.
A process called putrefaction happens after bacteria in the gastrointestinal tract eats through the abdominal organs, releasing horrid smells which attract insects.
Maggots laid by blowflies eat the rotting body tissue and can consume 60 per cent of the body’s tissue in a few weeks.
The remaining parts are then eaten by plants, insects and animals, which can take a year or more depending on how the body has been buried.
There are two stages of death – clinical and biological
Scientists have conducted much research into what happens to consciousness after death.

Without any scientific evidence of an afterlife, many religions offer their own explanation as to what happens after death.
Christians believe that after dying, spirits are sent to heaven or hell depending on their Earthly behaviour.
Depending on which strand of the religion you ask, sinners are sent to hell either for eternity or until they have repented their actions. Those who have lived their lives according to Christian principles will be sent to heaven.
Catholics believe in the idea of purgatory, a place between heaven and hell where sinners first go to repent for their wrong-doings.
The Islamic faith teaches that Allah will raise the dead on “The Last Day” – a date known only to him. On this day, he will judge all souls and send them to either paradise or hell.
Muslims believe that until then, the dead remain in their graves, where they will be sent visions of their fate.
According to Buddhists, spirits are reincarnated into new bodies until they achieve enlightenment. Upon doing so, they will exit the mortal coil and reach Nirvana – an “incomprehensible, indescribable, inconceivable and unutterable” place.
Many religions believe in the idea of an afterlife
Unlike most religions, the concept of an afterlife isn’t central to Judaism, instead it focuses on actions made in life.
There are some mentions of an afterlife in the religion, but not one divided into heaven and hell.
The Torah talks of an afterlife called Sheol – a shadowy place down in the centre of the Earth, where all souls go to without judgement.
