Oh, may your silhouette never dissolve on the beach;
may your eyelids never flutter into the empty distance.
Don't leave me for a second, my dearest,
because in that moment you'll have gone so far
I'll wander mazily over all the earth, asking,
Will you come back? Will you leave me here, dying?
See ya later, off to my new happy place! It never stops fascinating me how we earthlings are so elegantly designed to thrive in our home. Did you know that being under water, even just putting your face in water, lowers your heart-rate dramatically, eventually makes your spleen release boosts of extra red blood cells, and concentrates your blood to your brain and vital organs - all so you use less oxygen and can stay longer without running out. Not only that. For every 10 metres you ascend while holding your breath, your lungs half in size because of the way air shrinks with pressure. Below 40 metres, the squeeze is enough to collapse your lungs and kill you, but that's not what happens - instead, your body fills your lung tissues with blood so they keep safely expanded, allowing human beings to go beyond 200 meters deep and come up unharmed. As an extra safety measure, if we do black out underwater, our larynx automatically closes, stopping water from entering our lungs and giving our friends time to get us to the surface, where wind in our face makes the larynx open and us start breathing. Perfection! Even better - all mammals can do this, from mice to whales, and that is how seals, whales, dolphins and other sea-dwelling mammals are able to live as they do. It's called the mammalian dive reflex, and it's one of the more amazing things I learned about this week. This world and how beautifully adapted we are to live in it never cease to amaze me. We can do so much more than we think, and the systems we are part of are infinitely more elegant and intelligent than many of us realise. I'm grateful for every step, stroke or breath of awe and wonder I take on this planet 💚🐳🐋🐬🌍💙
