The human body is amazing
The other day I was lifting this jug of water and there was more in it than I thought, so I lifted with too little force, and water spilled. It made me stand in awe of just how intelligent the human body is.
We've all done this, lifting something we thought was going to be more heavy or less heavy. Our body instantly evaluates the weight of the object, based on the size, material, our history with it (did we just fill the jug?), and so many other factors, and uses the correct strength. Most of the time. Imagine trying to build a robot to replicate that.
And that's just a small sample. I remember studying computer vision back in college. Just the processing that needs to happen when you walk to make it seem like the world isn't bumping up and down is amazing.
Cherish your humanness. It's quite incredible.
