Yes - there are a lot of pickup trucks that park right outside my condo.  A lot.  Rather suspiciously a lot.  A lot of them have licence plates that start with "AL".  It wouldn't surprise me if many are diesel.

And although diesel definitely irritates my lungs, exposure to LED bulbs does as well.   LED bulbs also cause stiffness and tightening in my legs and torso.   It is dramatic -- not subtle.   They are as dangerous as heck for anyone who is vulnerable to it.  I can barely go into a department store now because of the pain and fatigue they cause.
