  • Leonard Hayflick "describes three phases in the life of a cell. At the start of his experiment he named the primary culture "phase one." Phase two is defined as the period when cells are proliferating -- Hayflick called it the time of "luxuriant growth". After months of doubling the cells eventually reach phase three, a phenomenon of senescence -- cell growth diminishes and then stops altogether."

    "If she were 10 or 15 years younger — Lynne is 39 — she might be Carrie Underwood or Kellie Pickler, blowing away the “American Idol�? panel with her earthy, passionate voice and booking a ride to the top of the charts. While 39 doesn’t necessarily mean senescence in pop music the way it once might have — Bruce Springsteen picked up his most recent No. 1 album at age 58; that’s eight years older than Frank Sinatra was when he recorded “Strangers in the Night�? — it is a little long in the tooth to be looking for your first big hit."

    The author might deserve some kind of vocabulary award.
