You were told wrong
It’s generally a good idea to chew on a question before answering. According to this guy, you should ponder a question while counting to 30. Only after that should you provide your answer. But what if you can’t think and count at the same time? After reaching 30, what’re you going to say? “Ah, iono LOL.”
Also, do you count Mississippi or not? Do you count be seconds, half-seconds, or at the pace you’re comfortable with? Hurry up, Adnan, stop counting to 30! We need to answer ASAP! Maybe this martial arts instructor needs to teach us how to react more quickly.
