Sustainable Architecture aka Healthy Homes

This is how homes should be built... Living Homes definitely fit my philosophy of life.

The ironic thing is that, while the houses in the videos are quite expensive, if this was how most homes were built then construction of homes in general would be much more affordable and more people would hopefully be able to own their own places. Not only that but everyone living inside would be healthier for the significant decrease or absence of synthetic chemicals and our healthcare costs (remember, it's all about the money) as a nation would drop significantly because people would suffer less from, among other things, various types of allergies and even cancer. Those FEMA trailers were really very concentrated (sick) examples of what we do to ourselves in real houses over a more protracted period.

Meanwhile, I'm regularly hit with a barrage of chemicals everyday in the form of paint fumes from renovation at work, second hand smoke outside my building and in town, exhaust from cars when I go for a walk, and pesticides in the grass I walk through...just to name a few. It's hard to know sometimes whether it's even safe to breathe.

* I did get the treadmill by the way. Not sure when they will be able to deliver it but I'm finally going to have a Nordictrack C2155. Now I just need some 3/4" plywood to build the table.

Question: If I breathe in more chemicals when I exercise than I do otherwise then is it healthier to go ahead and exercise anyway or stay inside (on my bum) with an air cleaner running?
