All animals have a certain set lifespan that occurs within a particular range. For instance, the end of a lifespan at the farthest age is typically around 116 years, give or take a few years. This is why no matter how healthy we are, we will not live to say 3000 years, which is considered the maximum lifespan of the sequoia tree. There are great differences across species with respect to lifespan therefore this must be a strong biological aspect to a species maximum life span. One speculation is the telomere length in chromosomes plays a role in the life span of Homo sapiens and other species of animals. For instance, shorter telomere correlate with a shorter life span. Each time a chromosome divides and makes a new cell, the telomeres decrease
