These are my thoughts after over 4 years of raising awareness, and meeting and speaking with a whole lot of these folks.
They are great thinkers, awesome listeners, and have spent a great deal of time attending one school or another. Most of them seem very physically fit.
Sometimes their research can be asking an awful lot of questions, recording the answers, and looking for common denominators. Sometimes their research is done with multimillion-dollar equipment, and animal or human tissue.
Sometimes they write research grants, which are very detailed request for money.
Sometimes they are actually called on to help raise money in front of a donor.
This information is what I have gleaned over a period of time and hope it is correct.
Oh, and one more thing:
Sometimes they are caregivers!
