The best way to save yourself is to memorize seed phrase.
Memorization is the worst possible way to back up your seed phrase.
You have to imprint it so well that even if you get amnesia, you should be able to recover that information.
People with amnesia (from any cause, of which there are
many) can forget their own name and fail to recognize their immediate family members. They can easily forget a seed phrase.
When you think you have truly memorized them and there is no way you'll forget that, then either destroy your seeds or come up with a better plan.[/quote
This is awful advice. If you are ever in a situation where your only back up is your memory, you should either immediately write down what you can remember and test it is still accurate, or you should move all your coins to a new wallet with a properly backed up seed phrase.
