There is a survey being conducted by Christine Milrod, PhD, of mature hobbyists over 60. She writes that this is an "understudied group of hobbyists, and yet they comprise a very important part of our hobbying community. We need to hear from them. What they want, what they like and what they do." Dr. Milrod is a legitimate clinical researcher. You can find out more about her here:

Email her or contact her directly through the website and she responds with a link to the survey. It is completely anonymous.
Just passing since any study provides a significant result when more participate. Also, the result may carry some benefits for who over 60 and when we reach that age.
