Thought I'd add my bit - I'm having a completely incompetent day so it'll be good to focus on things I can actually do!
Medical stuff - I'm a trained nurse and nurses are notoriously not great at first aid but better at nursing /infection control etc. Well, when I trained they did actually
do infection control. Not so sure now. I've also done chiropody.
I've seen some very scary first aiders with dodgy ideas over the years, so I can keep an eye on what they're doing!
Cooking - not bad, can make bread, jam, stews. I know a fair amount about vitamins/nutrition.
Gardening - yeah - I like growing herbs/fruits/veggies
Knitting - can do Aran jumpers. My sewing is crap however.
Crochet - beginners level, but can do blankets in granny squares
So that's it - when the shtf I can start a small community, all sat around wearing cabled hats eating jam butties with afghan blankets on their knees, and nicely manicured feet......Don't y'all rush now
