Immortal NØИ3§ΣN§∃

It's not that the secret 
To immortality is ever lost 
It's just the secret is useless 
To the Immortal Whö found it 
So rather than lost 
The secret is thrown out 
Or buried in a filing cabinet 
Somewhere in cubicle 427 
Until one day when cleaning 
An old coffee stained napkin 
With the "lost" secret 
Is again "found" - and then 
The Immortal says to its self: 
"What is this NØИ3§ΣN§∃?"
