 Well, I've become a lot more, and this is not to sound alarmist or to fearmonger, but I've become a lot more aware of my environment. I try to make sure that I'm breathing in clean air. I've replaced the air filters in my HVAC system in my home regularly. I have an air purifier because we know that indoor air can be up to 100 times more polluted than outdoor air, actually, due to the off gassing of our furniture, the exposure to volatile organic compounds and the like.
