Suggested word of the day - not in Shakespeare (he has nervy in the sense of sinewy, whence Keats got it). Interesting, in that the sense of "agitated" becomes, eg, "irritated" even "in a bad mood" in Italian, and cannot be used to express anxiety. Cp. German nervös and Spanish nervioso
Also interesting is the neurological sense of "nerves"("My nerves are bad tonight" - T S Eliot) perhaps overtaken by (pseudo-)science and also the (possibly obsolete) expression "What a nerve!" meaning "What cheek/impudence".
Oh, my, the Nerve of some people.
Glad you found it. What do you think.
I get nervous sometimes, and I find many people nervy or nervey, whatever it may be, used as in “cheek” above. Good topic, glad you found it. Let’s see where it goes.
In a confrontation with a predator, freezing just makes you look like a TV Dinner. Fighting just makes you harder to digest; flight makes you look like fast food: so take your pick.
When faced with a predator, that is probably what my reaction would be. Could not outrun a bear, puma, mountain lion, alligator. So, let them enjoy some bones (no meat here).
If sloths ever morph into carnivores, Luke will have nothing to fear. In all other predatory situations, he’s toast !
It isn’t the movement, it is the fear.
We have a sloth (don’t know the toe number) at our zoo Watched him/her one day, never saw a movement. Between steps, or asleep, one cannot tell.
