My backup is different, first I will make many micro sticks with gold and with that stick I will make my seeds in the form of words then I will combine them and make a gold necklace then one day on my wedding anniversary at night I will put that ornament around my wife's neck and say that as long as you have it around your neck I will be yours and if for any reason you lose it then I will also disappear from your life, that's enough for my security ! My security is final. If there is such security then no matter what happens, earthquake, Sunami, I will be able to keep my seeds secret.
