OK, $5 wrench will crack all, unless you sacrifice your life.

This is why you never keep all your crypto in one wallet. Split your coins up between a number of wallets, using a number of different mediums. Keep some of the wallets entirely hidden, for example by using a passphrase on top a seed phrase which has some coins stored in it, or by creating a hidden encryption volume, and putting one wallet in the non-hidden volume and a different wallet in the hidden volume. If you are a victim of a $5 wrench attack, you can hand over one or even several wallets which each contain a relatively small amount of bitcoin, while your main wallets stay hidden. If you do this, you need to make sure there is no obvious blockchain link between your wallets as well. If the wallet you hand over showed 5 BTC moving in a single transaction to a single address, and the coins haven't moved from that address, then that is a dead giveaway.

tattoo on your body may be on your arm or somewhere more private

This is a terrible idea. First of all, you have to expose your seed phrase to the tattoo artist. Unless you have it tattooed on your genitals, then you will expose it every time you go to the beach, go swimming, go tanning, or even just walk around on a hot day. It also becomes trivial for a $5 wrench attack as described above to be successful. Don't do this.

Put it in your memory I have mine in my head that's the most safer place on earth.

This is another bad idea, unless you also have it backed up on paper or metal. People naturally forget things all the time, not to mention the millions of people every single day who suffer an accident, head trauma, stroke, aneurysm, infection, seizure, etc., completely unexpectedly, which can result in memory loss. While it might be useful to be able to transport coins across a border, for example, by only remembering your seed, you should never rely on memory as your only form of back up.
