Lessons from Frank Sinatra

New York, New York: If you can make it there, you can make it anywhere.

Therefore, if there's a place you cannot make it, you cannot make it in New York.

Therefore, if you cannot survive in the vaccuum of space or the heart of a volcano, you cannot make it in New York.

Lesson to be learned from this: Everyone in New York City is a cyanobacterium. (EDIT: Or maybe a tardigrade.)
