Are questions not directly related to a health problem on-topic? For example, take the question
When I spend many hours in the sun, why do I feel fatigued afterwards?
or Brian Rushton's question
What is the purpose of the small holes in the maxilla?
Should these be considered on-topic? It seems like such questions would fit in well with the rest of the site, but would we need to modify the title or description of the site? Or would people assume such questions fit into "health-related questions"?
Should the description be something like "...or anyone with questions about health or human biology"?
