Can you think of another asset that enables you to store value more securely than bitcoin?  

For example, I may or may not have a large amount of bitcoins stored in my brain right now and no one can take those from me without my permission.  I could wash up on a beach in a foreign country, with tattered clothes, without ID or any other personal belongings, and if I can gain access to a computer with an internet connection I could still access my stored value.

Can you think of another way to store value like this?
