Oxygen is REQUIRED at 14k cabin altitude for pilots.  It is recommended well 
below that, and for good reason.  Hypoxia is a deadly killer that can sneak up 
well below 12k.  I have personally seen it impact crews in military aircraft 
between 10-13k.  Throw in medical factors, excitement, fatigue, and bad things 
can happen in the legal-without-oxygen realm.
Each pilot should evaluate their own need for oxygen above 8k and make the 
choice their best judgment dictates.  If you needed it and did not have it, 
your odds of living to remember that mistake are a lot less than if you had it, 
used it, and did not need it.
Of course, flying above 14k without oxygen is in violation of FARs and less 
than intelligent.
Fly safe.
