The life span of humans is determined by the so-called human genotype. However, this isn’t the only thing that determines the life span of humans. Environmental and nutrition factors also have an impact on life expectancy. All these factors determine the type of cells which the body creates in order to generate energy and repair damage.
For several decades, scientists have been working with mice, flies and worms in order to try and increase their life span. They found that by modifying the ‘Methuselah genes’, they can extend he life span of some animals. They believe that in the future, medicine and science will be able to create a new medicament that will increase the human life span.
