Part of the reason why humans age is because of antagonist pleiotropy.
Essentially the theory is that there genes that control more that phenotype. There are single genes which effect both how likely you are to die young and how fast you age. For example, if you have longer telomeres, you age slower but you are more likely to get cancer.
Natural selection optimizes for having the maximum number of offspring, so if you age too fast you won't have as many kids because you become infertile sooner, but if you die young you will also have fewer kids. So evolution comes to an equilibrium and this equilibrium says you can live about 90 years.
What is exciting is that there members of the animal kingdom, like elephants or Greenland sharks, or blue whales who have large bodies and long lifespans, but they don't immediately get cancer, like we would if we had bodies that big. Their evolutionary pressure was higher than ours, so their related genes are better than our local maxima. There is good reason to believe that humanity will soon acquire the genes of other species and become the best of all worlds in the animal kingdom. Humans born 50 years from now will make everyone today look subhuman, they will all be 7ft tall, be muscular and fit without trying, will all smart as Von Neumann, and they will look 25 years old when they're 80. The genetic singularity will soon be upon us.
