Emetophobia up. Some may have both. Some may have anxiety which makes them feel like they will throw up when they actually might not. People with emetophobia usually suffer from anxiety; they often may scream or cry when someone or something has been sick. The root word for emetophobia is "emesis", from the Greek word "emein", which means "an act or instance of vomiting", with "-phobia" meaning "an exaggerated usually inexplicable fear of a particular object, class of objects, or situation." People with emetophobia frequently report a vomit related traumatic event, such as a long bout of stomach flu, accidentally vomiting
Complexity function applicable, which may be taken to be uniformly recurrent or even uniquely ergodic. For "x" a real number and "b" an integer ≥ 2 then the complexity function of "x" in base "b" is the complexity function "p"("x","b","n") of the sequence of digits of "x" written in base "b". If "x" is an irrational number then "p"("x","b","n") ≥ "n"+1; if "x" is rational then "p"("x","b","n") ≤ "C" for some constant "C" depending on "x" and "b". It is conjectured that for algebraic irrational "x" the complexity is "b" (which would follow if all such numbers were normal) but all that
