How long does a person live in Buddhism?

In Abhidharma (“abhi-” roughly means “meta-,” so Abhidharma can be understood as meta-dharma, or “one level above dharma”), there is a concept called kṣaṇabhaṅga, or “momentary decay.” It holds that all existence lasts only for a split second, and this includes human beings. A related term is ēkacitta, or “one unit of consciousness,” according to which consciousness arises in discrete units rather than as a continuous stream. Under this understanding, is it fair to say that each person dies and is reborn from one split second to the next?
