If you haven’t already, I strongly urge everyone reading this comment to stand up and do a video walkthrough of your house, today. Do all of your book spines, jewellery, DVDs, games, clothes, tools, cutlery, etc. Take photos of your bike’s serial numbers (usually under the hub).
Store the videos and photos in a cloud album or even a free tier somewhere. Email it to yourself, whatever, just don’t forget to do it.
It might take half an hour or, but this evidence is priceless (in terms of time, but it does actually have an monetary value) if you ever need to claim insurance in case of a fire or buglary.
It simply isn’t possible to remember everything you own.
Some insurers demand photographic evidence of recent ownership - I found this out the hard way (who here has a photo of themselves with their bike?! I even had the receipt!)
