In mythological record of some religion, some human have been seen to have a lifespan of 500 year to 1000 years. Some have lived a lifespan of up to 5000 years. My question is; Is it possible for modern human to live up to such ages.
Based on scientific progress nowadays, it is possible that human can live up to 500 years but as for 1000 years or even 5000 years, I can't say for certain that we can live till that time.
Why to I believe that we can live up to 500 years old is because based on what is mentioned in many religion books, the average height of humans used to be 3.5 metres to 5 metres or more.
So based on this, we can assumed that the childhood of people in that era was longer, even the adulthood was longer and the old age was also longer. If childhood was longer, it means that the average strength of people of that era was higher, even their immunity system must be stronger and they lived a long life. This is because in the phase of childhood people grow stronger.
Later, I will provide a theory that can be used for research on how a human can live up to 500 years though science.
