> Again, there is literally no thing on Earth that can stop you from acting with dignity.

Nothing except serious illness.

Involuntarily vomiting your guts out is not dignified. Being paranoid and acting on your bizarre delusions is not dignified. Ranting on and on about the same things every few minutes because your short-term memory is gone is not dignified.

Maybe your definition is different from mine. Try to apply it the next time you see and smell a homeless person mumbling to themselves in public.
