Expanding the article's scope from "we should study mice of both sexes" to boiling the ocean with "we should IDIC mice studies" doesn't help here. Invoking age makes researchers more resistant to accounting for female biology in their research, because it gives them a ready excuse to say "we can't afford the combinatorial matrix of sex and age, so we're just going to study healthy adult males". In a world of theoretically infinite resources, it absolutely makes sense to widen the scope of mice studies to include all possible variations of mice, by sex and by age and by genetics. In today's actual world, it does not.
