Be warned though, using this stuff on your spouse or significant other could have undesired results. You may not want to know what you want to know.
It is good topic anyway. There are lot areas where it is cool to try to “read” other folks intentions, and try to hide yours.
One of those areas is trade in SHTF conditions. People often think that trade will be something like pleasant thing, while in reality it is gonna be (and it was) something like game who it is gonna outsmart other guy.
Things like hiding your intention,how high you gonna go, how much you need or have, how bad you want it, how dangerous you are, are becoming very important, and to read all of mentioned in other guy.
