Why we started loving springy surfaces?

It was not Newton who discovered gravity. The first visitations of fish into land happened sometime around 375 million years ago and “discovered” that they could no longer swim upwards. That's when we (yes, we are them) first learned about gravity. Though there are many hypotheses as to why that event occurred (like mating, avoiding predation, or simply just hanging around) it was a big turning point in the evolution of animal kingdom. I personally would go with the mating theory since it adds a romantic element to our first land invasion. Even we human love sex in strange locations, right? right???

So these fishes are presumed to have strong fins that helped them to crawl around the land and rudimentary lungs to breath atmospheric air. But there was a weak point, the backbone! The new buoyancy less, gravity-cursed world may have caused them literal backache since it was not simply designed for a terrestrial habitat.

So they all miserably failed in their quest right? No! By around 360mya, these hardy creatures were able to successfully colonise at least the immediate shores of the great seas.

Then several hundreds of millions of years have passed and many new fish species followed the same trend and some decided to turn back alongside rampant predation, natural selection and constant boning.

Now that we have permanently established ourselves in land, our bodies are still kind of favoring those long lost watery buoyant world our fish forefathers left behind. I think this is the reason why we terrestrial animals feel comfortable with springy cushiony surfaces because they mimic them. Swimmers among us already know the comfort of exercising in pools rather than a gym. Heck we can even spend a whole day on a beach and let devil face our “terrestrial” problems! In a pool, the buoyant atmosphere gives a push on our musculo-skeletal systems which is a “feel home experience” for all of us!

There is a reason why we love beaches so much, at the mere sight of it, the part of our DNA that our fish ancestors gave us, is giving us a desire to return there! It is still working in some remote part of the brain.
