For those hobbyists who are 60 years old, or older, there is a survey currently being conducted by Christine Milrod, PhD. The purpose of the study is to learn more about what motivates mature gents to participate in the hobby lifestyle. This is a legitimate, ground breaking study and the first to focus strictly on mature gents. Dr. Milrod is a legitimate clinical researcher. You can find out more about her here: www.sexandlifecoaching.com.
Obviously, participation is strictly voluntary. If interested, contact Dr. Milrod at info@sexandlifecoaching.com. She answers emails promptly. Alternately, you may PM me here and I will send you the link to the survey.
This is a blind scientific study. The results will likely be published in a scientific journal in late 2014 after it goes through peer review.
Thanks for your interest.
