Replace supplies that are past their shelf life:

• canned food — see expiry date on label (replacement will be every ~2-5 years, though it can go MUCH longer [2] if really needed)
• disposable butane lighters — shake next to your ear to confirm it still has a decent amount of fuel; light it once to confirm that the flint hasn't crumbled yet (replacement will be every ~5-20 years)
• glow sticks — replace every ~4 years
• batteries — alkaline batteries should be replaced every 7 years

Go through the paper forms and check if any information needs to be updated, every ~3 years.
