I personally cannot stand fragrances. I do not color my hair, nails. (I have long thought that hair color for women is dangerous-- for example--Lindane for head lice is absorbed thru the scalp so I expect many other things, esp those that remain on the head for time periods like dyes are problematic).

I have hardwood floors, and no carpeting.
I noticed some extra symptoms (my hands would go numb driving) last fall when I bought a new car. The smell lasted for several months, and I figured it wasn't doing me much good, breathing it for 1.5 hrs every day.

There was a guy in the news about a year or so ago, who had tests for
chemicals..he worked for a news agency. They found high levels of chemicials in him from flying in jets so much. They tested for over 1600 things I believe.

Right now flame retardants are getting alot of attention as thyroid disease inducers.
