veda #61 : Weird, Cow Can't Walk Downstairs

Day 61
"Why can't cow walk donwstairs?"

Weird fact tonight. I don't know which are more weird, the cow who can go upstairs but can go downstairs or down the hill, or me whom search for this explanation. Okay, here goes the story. Cow is a mammal that can go uphil or upstairs, but apparently, they can't go back to their first place, down stairs or downhill. There is a logical explanation for this. (really, i feel weirder than before...)

Now walking up, most of the weight of cow's body is down and back, and their knees bend helping them push themself up.
Now walking down, most of the weight is on their front legs, and their knees bend and point down the stairs, and with all the weight and the very real possibility that they could tumble down frontwards. They have four feet and must 'look down' when walking over an 'obstacle' ... that would throw their 'balance' off and they'd fall. A few horses can walk down stairs, but it takes contstant training and reinforcement, and most can't do it at all. They also can't walk up stairs (even those few who can walk down them) ... stairs are a 'human invention' because human feet are made longer and 'flatter' and have skin all over them, so when we are climbing up or down we want something fairly 'flat' to put both our feet and hands on ... when we realized that we don't 'slide backwards or forwards' with 'breaks' in the slope we invented stairs.

Think of it as you would a child, kids will first start to climb up steps, but getting them to go down takes a lot of patience and care by the parents, till they learn to walk down.

really...really not important...
