Mostly the same for me. I get extremely bored at work, on public transport etc so I end up thinking about what I would do. I don't have anything major like some of the American preppers do- there used to be a TV show with lots of them on it, including hippies who lived in a converted nuclear missile bunker and a man in California who had dug 40 or 50 foxholes around his property.
All I keep is some boil in the bag meals left over from ration packs (also got various bits and pieces left over, including just-add-water heating packs) and my multicam rig.
In an event which results in a breakdown of society, I'd fill my rig with:
Hydration pouch
Mess tins
Gas cooker
Camping lighter
Tea towel for silencing (and cleaning the tins)
Red and white light torches
Leatherman Pocket Survival Tool
Mora combat/hunting knife
Gerber STL 2.5 pocket knife
Boil in the bag meals and various snacks
I'd also grab my day sack and fill it with:
Multicam poncho- can be used as a waterproof coverall as well as a shelter
Bungees and tent pegs to secure the poncho and use it as a basha
Warm kit in the form of a fleece, spare socks, spare trousers, spare undies
Sleeping bag
Roll mat secured on the outside
Extra water bottle in an external pouch
Boil-in-bag meals I can't fit in my webbing
Spare cooking gas
Spare batteries
Ceramic knife sharpener
Any food I can grab from the shop across the road/loot from houses. Screw TVs, I want your beans!
