Lisa:
   Thank you!  I have been wondering the same thing.  Maybe I don't get
it, but feeling so great and having energy and a "goal" is all the
intoxication I need.  I walk out into my yard at 4:30 in the morning
with the soft breeze and the sun peaking up red on the horizon and what
would I miss with a drug or intoxicant in my body?  No thanks!
