Not a heart attack per se.
But related to “Women’s issues” some are.
Though admittedly there are not many examples that fall into that category.
I would ask though even if she is not “less likely” to call a male. if she feels more comfortable with a female, why shouldnt she have that option? Especially in a community that prides itself on tznius separate seating at weddings, buses., waiting rooms, all of a sudden when a women is at her most exposed we say no to sending a woman? (OF course if their is no woman available thats another story)
