Well I'm sure if the end of the world was nigh, it wouldn't matter what talents anyone had!
If you're referring to a total collapse of civilisation, lets see...
I'm a fairly decent shot, if memory serves from my time playing with air rifles. I could keep orphan babies alive as a wet nurse, as presumably there would be no formula, bottles or sterilising. I'm fairly good at backyard vegie production, and can fish, scale, clean, gut, cook, etc. I can do basic knitting and sewing. I can play basic guitar and piano. My DP is a carpenter, who also knows motorbikes, engines, and everything I've mentioned above except the wet nursing.
I'm also pregnant, so I can produce the next post-apocalyptic Messiah, if needs be.
