Bumping this for the daytime friends. 
In one of the declassified documents from 1977 released by the CIA, it’s mentioned that you can use the code 55515 to reduce pain from the physical body.
What You Do:
Focus your awareness on where your physical pain is coming from and repeat the numbers 5-5-5-1-5 until the pain is gone.
Anecdotal reports state an almost immediate reduce in pain after using this method.’
Placebo effect? Or Re-coding your body?
I did a bit more digging at it looks like there’s a gene discovered in 2000 (over 20 years later) that relates to pain perception also identified as 55515
