Walking on the Sea Bed

Ah, sir, live in the bosom of the waters! There alone is independence.

There I recognise no masters! There I am free.~
Jules Verne—2000 Leagues Under The Sea

Not too long ago I had  an email discussion with fellow Kurungabaa contributor, Ollie, about a photo of his friend freediving.  Over the course of the exchange we came to realize that humans possess many of the attributes of marine mammals.  While not fully aquatic, we share similarities like the practice of breath-hold diving that derive from what scientists call the mammalian diving reflex.  This adaptation permits us to lower our heart rates and release red blood cells to ultimately survive a deprivation of oxygen and extreme pressure at lower depths.

We have forgotten how to train our parts, however.   Many of us lift weights and run to maintain form but dismiss the importance of apnea training even when most of us (or at least this kook) must know how to hold our breath after punishing wipe-outs.  I think the video demonstrates what is achievable with the human body. We can recondition the function of our hearts and lungs to exist beneath the sea.   There are worlds to be explored and we have the organs to do it.   Be free and dive.
