I am a 74 year-old male, living in an old (1970's) 10' X 55' trailer house which shows
interior signs of previous mold, apparently largely from prior roof leaks. I put a new roof on shortly
after moving in, and it still seems good. I live in a quite dry climate  (Chico,  California) 
where we have long, hot summers.
I have developed a sensitivity to at least 1 version of mold existent in my trailer house. Subsequent to this
sensitivity, I have also acquired sensitivity to various chemicals which are common in today’s materials.
Normal persons would recognize no symptoms from normal levels of either of these things. The
Symptoms associated with my mold sensitivity have varied from being minor to
somewhat debilitating. It is not a normal life for me anymore, though I can still work some, and have
not moved. I have several times thought I was in a 'death spiral', with Mr. Mold in control.
