It has to be someone we trust with our life. I don't think I would want to pass out such personal information to anyone right now. Even though we understand that life isn't as blossom as it seems and in a blink what happens next night be undefined we still might have to trust us with our seeds. There are so many ways we can do this, either using a dead man's lock or just giving your loved ones some kind of hints so when something happens, they will know what to do with your seeds.
