A vague one, yes. Things like we went through on the last planet aren't as common, but running into problems or stressful situations? That's more so. We tend to go through a 'stress' episode, to speak, and then we get something quieter, so to speak.

If you play into this all being for a TV show, it makes sense. My personal theory is they are testing how we react to these situations, though some of them haven't felt as... controlled as others.
