If you like the idea of a brain wallet but fear the risks, consider a wallet.

A brain wallet is a Bitcoin private key derived from a (memorable sentence) via a hash function. If someone guesses your passphrase, they steal your funds — so it's high-risk unless the passphrase has very high entropy. This hybrid model protects against fire (you have

This hybrid model protects against fire (you have your memory) AND amnesia (you have the physical backup).
