When I saw the video and heard the speaker say that each of us is a keeper of a invisible zoo I found it strange and super weird and it just grossed me out. I mean to think that your keeping a huge invisible zoo in your body is just plain gross. I can’t even explain it. When the speaker said that we are never alone that we have creatures inside our bodies. I was freaked out even though I already knew  we had creatures like bacteria on us but to see the images of the bacteria and everything else we have I just don’t know how to explain it because it’s just so weird. I learned that we have something (not sure what it is) around our eyes and that scientist don’t know why we do and what they are there for. I also learned that bacteria always multiples it self into huge numbers. I also learned that when your alone and no one's around you could always say to yourself that your not alone that you have a huge invisible zoo on you!
