Are they still there? Do they backup the wallet you remember they are for? Does anyone else have access to the safe? Are they a single point of failure or do you use a passphrase/multisig/another tool? When was the last time you attempted signing a txn? Is the safe at the same location as your signer? Even more tinfoil hat: What are the chances the safe was replaced with a replica? Where were you when you generated the seed, were there any cameras around? Was the tool used ever determined to be low entropy?
