If someone says to you: "Whatever you do...don't look down!" ...do you look down?

You probably would right? Are we programmed to question an advisory like this? or maybe to examine the situation ourselves and make up our own minds? Kinda like if you’re with someone and they cover their nose and say: “Oh my god, what is that smell?!” what’s the next thing you do….take a big whiff and see for yourself right?
