Sixty years of unwitting exposure. I think about that a lot now. Sixty years of consumption that nobody — not my doctor, not my employer, not the federal government — ever once disclosed to me.

I worked in civil infrastructure for four decades. I knew what DHMO did to bridges, to pipes, to roadbeds. I quantified it. I wrote reports. And every day on the job site, I drank from the same coolers everyone else did.

When I retired, I had time to think. I read the Citizens Against DHMO research and it crystallized something I had felt for years without being able to name. We engineer around this substance professionally and consume it personally without question. It is a strange way to live.

I tell my grandchildren: ask questions. The answers may surprise you. The answers may upset the people you ask. Ask anyway.
