So, while I'm going to curb my hyper sensitivity and passive aggressive nature for the sake of a public forum that I do respect, will you please try not to come across as snarky? 

This went right over subfloor- but it can be sensitive to height differences at connections and gaps. 

The difference is over time I have hammered that nerve so that it's not so sensitive anymore, and every time I do, it gets a little easier. 

It really could just be they are more sensitive to the water.

Why is it so sensitive or is it just "who" posted it?

If there's a hole, it may be a red flag.b) sensitivity analysis: I examine all the assumptions, and make sure I can live with the worst case scenarios.c) "Stall and see": if they are getting money over multiple years, and there is no penalty for investing later, I would usually wait so I get some real performance data, versus having to look at theoretical pro forma information.d) Recession stress test: I will not invest in anything, until I subject it to recession level stress and see if I can live with the result.

I'm chemically sensitive.

Once they're producing, the labor requirements are a lot less.A place like Houston or Tulsa is less sensitive to this because there are other jobs.  

If you are referring to nuclear weapons, then the best controls for them, so far, have been controlling the supply of critical parts through concerted international export controls on sensitive technology.We need to remember that Mexico is not directly connected to Iran, etc.

Not much i'll hire people to do, unless there is tim sensitivity.
