their eyes and behaviour; Tolkien also stated that Elves do experience change and aging—not by growing old, but by altering other features of their appearance. The combination of physical youth and immense mental maturity can render the perceived age of an Elf undefinable and alien by mortal standards. The Aes Sedai of Robert Jordan's Wheel of Time series are described as ageless. A feature of their magical abilities extends life and makes their age difficult to place despite their white hair and physical frailty. Television and soap operas On television, the process of a character (usually a child) aging unusually fast has been a common feature in soap operas and is known as Soap Opera Rapid Aging Syndrome or "SORAS". The reverse effect, where characters fail to age at the typical rate they should or in fact become younger, is known by a more recent, opposite term known as de-SORAS. On the British television show Doctor Who, which involves time travel, all of the Doctor's incarnations appear not to age, except for the First Doctor. It's also implied on The Sarah Jane Adventures episode "Death of the Doctor" that the Doctor's first companions Ian Chesterton and Barbara Wright have never aged since their travels; Also, despite the fact that 10 years of the life of the Pond-Williams passed between "The Eleventh Hour" and "The Angels Take Manhattan", they didn't show any major traits associated with aging. Several characters on ABC's 2011 TV series Once Upon a Time do not age, either through the effects of the Dark Curse or spending time in Neverland; in the case of Hook, both are true. Other characters, such as Rumplestiltskin or Merlin and his apprentice, do not age due to the fact that they possess immortality.
