Some thoughts: - The lady with short hair seems to be stuck in a binge-restrict cycle. Also gives me junkorexic vibes. - Couldn't it be that people who spend more time looking at worried phases have a natural drive to worry about others? maybe they unconciously try to figure out what's wrong with them? I know there's a correlation with more diverse gut bacteria > focusing more on happy phases, but i don't think the test is properly designed to measure a person's optimism let alone their outlook on life. Finally, let's remember that correlation is not causation, gut bacteria has also been shown to react negatively to stressful environments. What if the correlation works inversely, that is, people who are depressed impact negatively their gut bacteria? Again, the test proposed wouldn't work well to measure such a mindset, so my counter-argument is flawed from the start, but is still something interesting to think about.

I'm amazed that the pasturizing doesn't kill the good bacteria too tho. But breast milk is far easier for a baby to digest.
