Recent scientific experiments (in Australia) have ended years of debate about 
where the "trigger" to breath originates. They effectively unplugged the brain 
from the body, and put the subject on a respiritory machine. By stopping blood 
flow to one arm for 30 mins, the subject could indicate how he felt, eg OK or 
DISCOMFORT or EXTREME DISCOMFORT. 

They then played around with the CO2 levels in the respiritory machine. The 
subject felt extreme discomfort when the CO2 level was high.

Is it possible that if the trigger is a chemical switch in the brain that (in 
Jason's case) it is unbalanced, and the body responds (just like the blind have 
with thier hearing) by becoming more sensitive to the low oxygen partial 
pressure in the blood?  


In any case, we all know here in Sydney that Jason is indeed an 
extraterrestial, of unknown origin.

Rod.
