Yes, I answer the questions, and I don't mind at all. As a researcher, I've used census data to look at policy questions that are really important---how many people want a job but have given up looking? How many people are living in poverty? etc. Understanding that stuff helps drive good policy, policy that helps people.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
