The Hayflick Limit

Shortlisted for the 2010 Trillium Book Award for Poetry! To be human is to cope with knowing. In the early sixties, Leonard Hayflick determined that healthy cells can divide only a finite number of times. Known as the Hayflick Limit, the law sets an unsurpassable lifespan for our species at just over 120 years. The Hayflick Limit concerns itself with boundaries of the cosmic and sub-atomic -- how the mind contains both -- and the sadsack creatures in the nexus, human beings. What does it mean to be an intelligent species? What does it mean to be an intelligent person? Shifting focus between the limits of the telescope and the limits of the microscope, the poems in Matthew Tierney's second collection place a premium on inventiveness while embracing extremes of fear, pain, cognition and time. With demotic verve and a humming line, he gives voice to a range of characters who scrape out meaning in a carnivalesque universe that has birthed black holes and Warner Bros. cartoons, murky market economies, murkier quantum laws, Vincent Price, Molotov cocktails, seedless grapes, Area 51 and competing Theories of Everything.
