Y’all ever just suddenly have the overwhelming urge to swim??? Like not actively but you just wanna,,, be in the water and have some Peace
Yes it’s called the mammalian diving response and it’s also why doing face masks and taking a shower is soothing. Our amphibian ancestors used this mechanism to slow down the heartbeat and lower body temperature so as not to waste calories while swimming (which is very calorie intensive). It makes you feel safe because predators are less likely to get you in water than on land. The fish brain is alive and well in all of us.
It’s literally activated by putting water on the face.

Creepy or adorable? Researchers at Harvard University have demonstrated the first autonomous, untethered, entirely soft robot: the octobot.
Instead of being controlled by electronics, the robot’s logic board is powered by chemical reactions and fluid passing along tiny channels. Scientist have struggled to create completely soft robots because rigid components like circuit boards, power sources and electronic controls are difficult to replace.
