Nathan is a student who has been diagnosed with bronchitis due to a bacterial infection.
[coughing]
Man, I wish all bacteria would disappear so I wouldn't be sick. [Music]
Man, I feel a lot better now. Did my wish actually come true?
Boy, I do feel super hungry, though.
Ooh, macadamia nuts! [Music]
Um. Why does my stomach hurt so much? I thought I wished all the bacteria away.
Well, you see, dear brother, the reason why you're
having a stomachache is because you wish for all the bacteria away.
Some bacteria are actually very beneficial to human health.
Wait, but I thought all bacteria were harmful.
[Music]
Let's talk about bacteria.
Yes, exactly. Bacteria are essential for your digestion. For example,
one bacteria essential for manufacturing vitamin K in your body is lactobacillus acidophilus.
These bacteria can help you break down food and absorb nutrients.
Then I can just wish away all the harmful bacteria like salmonella and E coli?
So, some strands of bad bacteria very beneficial. For example, versions of E coli release
enzymes to promote digestion and play an important role in the processing of food.
So, now you see, my dear brother, that is why we cannot wish all
the bacteria away and why you got a stomach if eating a macadamia nut.
Oh, man. I shouldn't have wished all the bacteria away.
Well, let's wait for another start and bring our little friends back.
