What happens when you die biologically?
After death, the human body undergoes a series of biological changes, collectively referred to as decomposition. These changes stem from two key factors: the cessation of biological functions within the body. the spread and activity of bacteria after death.
What happens to humans after they die?
Decomposition begins several minutes after death with a process called autolysis, or self-digestion. Soon after the heart stops beating, cells become deprived of oxygen, and their acidity increases as the toxic by-products of chemical reactions begin to accumulate inside them.
What do we see when we die?
Seeing a White Light
One of the most common and well-known near-death experiences for those who die and come back is seeing a bright, white light. This white light isn’t something to be afraid of. In fact, most report it coming with a sense of peace or even happiness.

The important findings, along with observations of long-time palliative care doctors and nurses, show: Brain activity supports that a dying patient most likely can hear. Even if awareness of sound cannot be communicated due to loss of motor responses, the value of verbal interactions is measurable and positive.
Why do we die?
We die naturally because our cells die. After they’ve done their job, billions of cells in your body die each day and make way for new cells. Old cells age us. Inside a cell, telomeres at the end of each chromosome contain genetic information that gets clipped away with each cell division.
Do we live forever?
No matter how advanced technology gets, it might be impossible for our bodies to go on forever. Some researchers believe there’s a limit on how long it’s physically possible to live: perhaps 125 years.
Why do we age and die?
Your cells are programmed to divide, multiply, and perform basic biological functions. But the more cells divide, the older they get. In turn, cells eventually lose their ability to function properly.

What will be the life expectancy in 3000?
Plus, there will be an increase in both the average height and longevity of most people in general. That means, in the year 3000 people will be about six feet tall and live to be 120 years old, on average. They will also tend to experience a slight reduction in the size of their mouths, as well.

Aubrey de Grey is one of the world’s leading – and most talked-about – biomedical gerontologists. Meet the man who believes that the first person to live to 1,000 years of age has already been born. Aubrey de Grey is one of the chief proponents of research utilising genomics to explore longevity.
What will humans look like in 100000 years?
100,000 Years From Today
We will also have larger nostrils, to make breathing easier in new environments that may not be on earth. Denser hair helps to prevent heat loss from their even larger heads. Our ability to control human biology means that the man and woman of the future will have perfectly symmetrical faces.
