Not an astronomy question, rather biology.
It has to do with the way cells replicate: the strands of DNA (that control how new cells are built) lose a bit of information every time they are copied and, despite lots of built in redundancy, enough information is lost that cell reconstruction begins to falter after some time. We age and our organs begin to work less efficiently.
Takes, on average, a little over 70 years.
