I am confused: https://en.wikipedia.org/wiki/Natural_number States that Some definitions, including the standard ISO 80000-2,[3][a] begin the natural numbers with 0, so I thought this is standard emacs/org uses.

Uwe -- I strongly condemn Putin's war of aggression against the Ukraine. I support to deliver weapons to Ukraine's military. I support the ban of Russia from SWIFT. I support the EU membership of the Ukraine.
