Wise advice, Sue.
There are many reasonable ways to approach the subject that aren't macho, guns blazing, end-of-the-world with zombies etc. That stuff spells k-o-o-k to a lot of of women.
Red Cross publications?
First-aid courses?
Environment - reducing impact, 100-mile diet, etc.?
Self-sufficiency - gardening and storing produce?
Pandemic planning - from the local health authority?
There's also the historical angle. Pioneer women -- our grandmothers and great-grandmothers -- knew more about "survival" in a practical everyday sense than the rest of us put together. There was no macho about it; it was just life, and most of those skills hold up today.
