Pleased to see Emily here. Bring her more often 🙂

[jaschabull]

No words for how happy it makes me to see Emily again. You have been missed!

I am recovering from rotator cuff surgery on my left shoulder. In my opinion, the shoulder is the weirdest, most bizarre joint in the human body. My orthopedic surgeon and my physical therapist agree with me! Great video, Hank and Emily.

[emmanuelweinman]

After 3 surgeries on my shoulder due to a torn labrum, I can personally testify how important shoulders are. They hold us up and allow us to lift others up. Without both shoulders being functional, the whole spine and body is affected.

Fun fact: this is also the reason why whales/dolphins flap their tails up and down rather than side to side like fish.

The ancestors of whales and dolphins were somewhat wolf like. Imagine a running greyhound and how its spine contracts vertically with each stride. So proto whales kept the same direction of flex when evolving into a fully aquatic life style.

Reptiles however, waddle their spines side to side when they walk. So when some of them decided to go full aqua, they flap their tails horizontally like fish. Go look up the extinct marine dino Ichthyosaur. It’s fascinating.

Emily is back!!! It still has brains on it!

[TearyEyesAnderson]

Oh my goosh... Emily is back... :o Miss seeing her in Brain Scoop, and even was hoping for more of her Science art videos on her personal YouTube. But she's back now. Awhhh, , puppy dog eyes. Hope to see more shows with her soon, whether SciShow or something else.

I really enjoyed this video. Emily's enthusiasm for the subject made it so engaging. I hope she becomes a regular presenter too.

I love this format :) Reaching out to really knowledgeable people out of your regular team is a wonderful idea.

Thank you Emily and SciShow! So good to see her again

[terryenby]

My shoulders love popping out of place all day every day. Thank you for managing to make me feel grateful for them still!

Also, Emily your necklace and glasses are SO COOL! Your whole aesthetic is beautiful.

Have a fantastic weekend everyone! 💜

Please give us MORE EMILY GRASLIE! Awesome and interesting presentation.

[ANONMD]

I've read that these mobile adaptable shoulders are the most frequently injured joint in the human body due in part to the extreme mobility provided. Guess there's always trade-offs.

[RemyStripsForSoup]
