[R-390] Ramblings on Calibration

[Barry Hauser]

Wow Gord ...

Does this mean the venerable R-390A will be "instrumental" in saving a lot 
of us from clots of doom?

For the heck of it, try a small dose of DeOxit on some sample clots. 
Probably work better. If Caig could develop a non-toxic formula the added 
advantage is that the D5-V (vascular) would leave behind a protective 
coating to prevent further buildup.  Side benefits -- possibly improved 
synaptic connections between neurons in the nervous system and cerebral 
cortex.  Not to mention that DeOxit is, uh, an anti-oxidant - of sorts. 
Also, it's red, so won't clash color-wise.

Only one fly in the ointment - how to cure the patient without poisoning him 
to death -- but that's a classic drug development problem.  And then, even 
after approval .. well you all know about that.  Of course, blood tests 
would be needed to monitor liver function -- as with all of the meds these 
days.  However, DeOxit may well clean the crud out of those too.

Interesting application -- yours -- though.

Barry
