When you are out mowing the grass or doing yard work and you start to feel tired or sick, do you really think it is an allergic reaction to the nature around you?  Think again.  It happens to me all the time, but I know I am reacting to the toxic chemicals coming out of  dryer vents, which are blowing laundry soap and fabric softener.  Sad but true, we cannot even go for a walk in our own neighborhood to get fresh air.
