Deletion of Circadian advantage

Comment: Doesn't matter if it is rare, references establish it is notable. No indication of a  problem. Topic is not discussed in Circadian rhythm or Jet lag. Could be merged into Circadian rhythm and/or Jet lag but it is not obvious how to do that or how that would improve things. Best to keep it as it is
Stance: keep
