re: What is something you have developed an allergic reaction to as you have aged?

The fungicide farmers spray on crops around me, mainly soy beans and corn. One year it just started giving me a headache and foggy-headed feeling. It starts slow and builds and lass for a few weeks during the late Spring when they spray it.

I didn't used to have it. It just sort of developed one year. I'm usually miserable for the better part of a month every year.
