About 5 weeks ago our household received a letter from the CDC saying we had been selected to participate in one of their surveys. I chose to ignore it. I have since received 2 postcards and a phone call urging me to participate. Well, last night I looked up what kind of panel this was and guess what? It's about smoking-knpanel. Hmmm, I suspect we were not "randomly" selected. Do you think those of us who signed the White House petition might be targeted? This is creepy to me, or am I overreacting?
