I definitely can. But it's one thing to memorize it and quite another to keep it in your memory for a very long time. Especially when you don't recite it or make use of it every once in a while, it's just a matter of time before you will forget it. So for your security it's best to just write it down in several copies and keep it in different locations.

The benefit from memorizing your recovery phrase is that nobody can steal if from you. The setback is that it is risky. It's very possible you'll forget it not only because memories fade over time but also because you could develop health conditions that weaken your memory perhaps because of accident or old age. Another setback is that your coins would die with you. Your family can't inherit it from you.

I'm too old for it and probably won't be taking that risk to memorize without having a back up.

@OP, how not secure is the place where you're putting that keys of your wallet? Don't do that, put it somewhere safe that no one is going to suspect that it's something valuable to you.

If the place you're keeping it is exposed, you're going to regret that later on. Please put it somewhere safer in your house and I know that each house has that kind of place.

Setbacks are more than benefits and you should never use your brain to back up your wallet seed phrase. Your brain can have sudden unexpected damage and memory can be lost forever, consequently your fund will be lost forever too.

How to back up a seed phrase

Even the owner can lose access to his bitcoins if memory was lost by whatsoever reasons.

I'm not sure if I can memorize my seed phrase, but let's try.

Sad but truth and I pray for the peace of everyone in Gaza.

But I guess that since OP is able to post in here and for sure that he's in a safer place. So, that's possible that he's got a safe place in his house or apartment or wherever he is living right now.

He better find one for his own safekeeping.

I know that the shortest pencil is sharper than the biggest brain and as human beings we tend to forget things, especially if it is something like seed phrase that is supposed to be kept for many years. The pressures of everyday activities and challenges can make us to forget some minor details and in the case of seed phrase, if a person forgets one word of it, then it has ruined the rest that you remember, so it is better to have more than one copy and hide them in different safe locations where you can easily access them. Although it is not a bad idea to memorize seed phrase, but it will be a very bad idea to rely solely on memorizing it without having physical copies Incase you forget, so a person that wants to memorize from where they wrote the phrase periodically is a good idea too.

It's possible to memorize a 12-letter seed phrase, but memorizing a 24-letter seed phrase might be very difficult, since the letters are random and you need to memorize them in the right order. However, if you succeed in memorizing it, of course the advantage is that you no longer need to copy-paste or look at the paper where you wrote down the seed phrase - because you can write it directly from your head. But since the human brain is fallible, there is a possibility that the seed phrases you memorized are not in the correct sequence or you forgot some of them, that is the problem.

I concur to this memorizing such important life investment security like I do called it is very dangerous the best one can do is to right it down and keep in place where it will not be misplaced or been take by another person.
Then one also need to know the least five words or figure from the starting and also the five ending figure or work as that can help so easily in remembering the key or pass phrase.

Writing your recovery phrase on a piece of paper is not really the best option, and trying to memorize your recovery phrase is even worse. If you are storing your recovery phrase, it’s better if you carve it on a small piece of iron steel, then you can store it in a different location. Iron steel is always difficult to damage, so if there is a fire accident or if water touches it, then it’s not going to get damaged compared to if it’s written on paper. If you decide to memorize your recovery phrase, if anything happens and you forget some of it, then that means you already lost access to the wallet. We can’t be too confident about our brains, if you memorize your recovery phrase, you might remember everything at the early stage, but with time you might start forgetting some, so it’s totally wrong to memorize your recovery phrase as your only backup plan.

Just because a piece of paper doesn't take up much space it's not safe? For me there is still a safe place unless you know it yourself, we know where the safe place is to keep a piece of seed phrase notes.

I don't memorize seed phrases in my brain. It's human nature to forget especially for a long time unless you keep the notes by memorizing them in your brain then it's not a problem in my opinion.

It's just that it's enough, with a paper note because for me it feels safe.
