Several decades ago I worked in an office building on Biscayne Boulevard in Miami doing social services. There was lots of paperwork and I spent hours at my desk. Most afternoons by 2 PM I had a headache if I spent the day in the office. My mind was fuzzy. I had read about “sick buildings” and wondered if the building was the problem. No windows could be opened, and there was poor air circulation. What could I do? Since I often made home or program visits to complete paperwork or to monitor my clients, I began to arrange some visits daily and if possible, made many visits in the afternoon. I no longer had headaches. I was lucky that I did field work as most office workers and homeowners do not have the luxury to leave.
