The wonder of the legs. I don't know if most people notice how wonderful our legs work, and cooperate with the whole body to give enjoyable and fluid motions.
When you walk across the grass, you hardly feel the small bumps of the soil, and little uneven rocks.
When you walk up or down a few steps of a stair, you don't have to think twice.
When you walk up or down hill, and leisurely, you don't feel much change.
If there is a bump at the door, you just step over it.
And you will probably not notice the very slightly raised carpet surface as you walk from a tile room to the carpeted room.
When walking on a cemented surface, you will just assume it is flat.
Why am I saying all of this?
I just recently moved (this is the nth time) to my new dorm room. I used a 4-wheel cart to transferred my boxes, and it helped a lot with the weight. However, what I noticed is that the cart feels the effect of every little bumps on the road, henceforth, my arms do, too. On the cemented pathway, it rocks gently. On the paved pathway, it jumps at every grid. Even the slightest bump where the door frame is, and between the carpet and the tile floor halt the rolling. Not to mention that pushing it through grass is extremely bumpy. And if you are going down hill or uphill, it gets out of hand.
So see. Legs are just wonderful.
