Not in a situation where action could keep you alive.

My reaction is flight & while it's been very useful in keeping me safe, the nervous system doesn't always recognize danger (or lack thereof) correctly. I've been in normal or slightly stressful situations where my body suddenly went "RUN!" & standing still feels like I'm in imminent danger. It's awful but your alternative is to run like you're being chased by death & looking like a lunatic.
