Indeed.....
The OP was meant to be a bit tongue in cheek.
The first thing our dean said to us as a newly assembled group bright eyed and bushy tailed students on our first day at University was:
"Remember. Half of what you are taught here in the next 7 years and half of what you may be told thereafter is complete and utter rubbish and half will be true. Your job and career will be to determine which half is which!"
In the 33 years since, I have found his statement to be true.
Every "fact" needs to be tested, assumptions examined and the evidence properly weighed; and even then you do not necessarily have an answer. Time usually is the ultimate judge.
The main problem we have is that few people do this and even fewer will believe evidence even when they are slapped about the gills with it!
This study is, after all, about mice not men; lack of sleep was but one factor in the experiment and we are not told of any others in this short snippet; it may be purely incidental!
