No, questions on the Physical Fitness site are
not within the scope of Biology. Every Stack Exchange site has an expert audience. The expert audience for the FItness site is professional trainers and nutritionists. The questions there are about those disciplines. These are known, respected professions. Biology's expert audience is scientists studying the field of Biology. This "Mind" proposal
has no expert audience. It is an overlap with the Cognitive Sciences site which is currently in beta. —
