Researchers can learn a lot with your genetic information, even when you skip survey questions

Imagine you agreed to be part of a new and exciting long-term research study to better understand human health and behavior. For the past few years, you’ve been visiting a collection site where you fill out some questionnaires about your health and daily activities. Research assistants take your height, weight and some other physical characteristics about you. Because you agreed to contribute your genetic data to the study, you also provided a saliva sample during your first visit.
