Reply to Taheri and Thomas: is sleep duration associated with obesity-U cannot be serious.

摘要

Taheri and Thomas seem to have been sensitised by our review exploring the ever expanding and increasingly contradictory literature on the association of obesity and sleep duration. Their final sentence seems to suggest that we are pessimists "glass half empty" in contrast to their more optimistic view on this subject "glass half full". Their comment brings to mind the great cartoonist Gary Larson's version of the 4 types of person-4 men all looking at a glass filled 50% with water on a bench. One says happily "the glass is half full", the second says sadly "the glass is half empty", the third, looking confused says "is it half full or is it half empty?". The fourth, looking angry says "Hey, I ordered a cheeseburger!". In a spirit of collegial repartee, we would suggest we are actually the confused "is it half full or is it half empty?" types while Taheri and Thomas are already demanding the full cheeseburger meal.
