Ultralighters, what UL gear/habit have you taken off the trail and into everyday life?

To kick things off, I observed a few behaviours that started on the trail and are now routine: - carry stock cubes to bulk out food and sachets of sauce - emergency supply of milk powder - 9 meals out of 10 are couscous - never abide with a heavy (>800g) unloaded backpack - froggs toggs waterproof as streetwear - walk fast and do not stop to talk

Naturally, my fashion sense (fleeces, hiking boots, down jacket) was UL to start with so I hardly think this counts.

Edit: my memory has been jogged, forgot about darn tough socks and keeping a couple cable ties close to hand
