Harvard professor Daniel Lieberman has ditched his trainers and started running barefoot. His research shows that barefoot runners, who tend to land on their fore-foot, generate less impact shock than runners in sports shoes who land heel first. This makes barefoot running comfortable and could... More

nature's way is the best way :)

If you step on shit;your fucked

What happens when you step on broken glass??
newhopecalgary Says:
Ever think about why we were created to run, especially long distances? Ever wonder about the joy we get from running? youtube.com/watch?v=T0cZNKTIweQ
jbocca70 Says:
thats how you get flatfoot?
jshealy Says:
the only point I've tried to prove has been proved above-there are no missing links. That eliminates descendency from apes and natural selection. I believe in a multifactoral approach to the beginning. I consider myself more of a philosopher/theologian but I feel those are very valid to the discussion. Science CANNOT exist alone.
orangeiceice12 Says:
As a Christian, I don't find God and natural processes unfolding to be incompatible at all (especially in terms of big bang; nihil ex nihilo after all). So I guess what Im asking is if you deny human origination from apes or, even deeper, if you deny any species can come from any other species, then what exactly can be offered as a theory to replace those ideas, which are clearly flawed, and yet do a very good job of explaining so much?
orangeiceice12 Says:
I mean you can say panspermia or you can say God but that really just removes the burden of proof to a more distant location. I think young earth creationism is no longer held for a very good reason, both for textual reasons and for evidential. I think a too-literalist interpretation of Genesis 1-3 will lead one to miss the real lesson of Adam and Eve, Cain and Abel, etc. Also there are clearly other humans descended from other sources, such as the men in the Land of Nod.
orangeiceice12 Says:
Well the third is definitely true cuz its directly observable, i.e. bacteria adapting to new antibiotics. Natural selection I believe is being partly discredited as the mechanism of evolution; there are clearly other mechanisms in play (such as 'mathematical necessity', as in the way proteins fold). Its the first one that bothers me. If you say okay humans didnt descend from a common ancestor to our closest living relatives, the primates, then all of a sudden theres a massive gap of explanation
jshealy Says:
the first two for sure. and possibly the third.
orangeiceice12 Says:
I dont understand. Are you denying human origination from apes, natural selection, or evolution entirely?
orangeiceice12 Says:
No, actually, shoes cushion your heel which encourages heel striking and shifts your posture so that more braking happens and your hips and knees absorb more pressure, thus causing injury (i.e. the impact transient referred to in the vid). Its been found that ~90% of running injuries come from using athletic shoes. You can however use thin-soled minimalist shoes to get the benefits of barefoot without the need for toughening the feet. Google huaraches or vibrams
SOodd14 Says:
Regardless of what your form entails won't running without absorption create impact on your joints? Wouldn't it be more practical to train yourself to have good posture and still use a padded shoe?
jshealy Says:
no, you misunderstand. You see, gravity has been classed as a law. That means it has never been found to operate differently in any experiment. 10 times out of ten it functions as expected. The theory of evolution does not nearly have that track record. And again, maybe you read the discussion above. There are mountains of evidence against it as well. We remain open-minded.
hombrearena Says:
You still misunderstand. If I hold an apple in the air and let go, scientific theory states that it will fall to Earth. I don't know for certain that it will - in the sense that nothing is ever known for certain - but the theory is extremely well established and I am confident of the outcome. Masses of experimental evidence support the theory of gravity. Likewise, the theory of evolution. There are vast mountains of supporting evidence and nothing to suggest it is false. We remain open-minded.
jshealy Says:
the words are STILL exactly the same. You see, in an effort to give more creedence to your point of view, you've redefined the word to mean fact, but by it's classical definition there is ALWAYS room for error, else it would be called the "Fact" of evolution. Most open minded people accept that there COULD or MIGHT be other points of view, but the nice thing, for you, if you consider theory a fact is you don't have to. Pretty arrogant, but still not the case. You don't define absolute truth.
hombrearena Says:
jshealy, you are making the mistake of confusing one common meaning of the word 'theory' (a guess) with a scientific theory. A scientific theory is the highest standard of knowledge available. There is nothing higher. Scientific laws are observed facts about reality. Scientific theories provide an explanation for observed facts, can make predictions based on that explanation, and can be tested. Should a theory fail any test, it must be modified or discarded.
volapuk49 Says:
Really great video. thanks. I want to do this but my left ankle collapses in internal rotation with strike of foot. I will do it slowly at first and see what happens.
jshealy Says:
once again, no they haven't National Geography propagandist. They have been proved all one species, not a combination of 2. Genetics and nutrition aside, there may be resemblances, but still NOT a combination of 2 species. You hold no corner, at all, on absolute truth. Only your version of truth.
dman519 Says:
Never been found according to you. You would deny, deny, deny no matter how much evidence was thrown at you, that's your problem. Fossils have been found for Australopithecus anamensis, A. afarensis, A. sediba, A. africanus, homo habilis, homo neanderthalensis, and homo erectus, to name a few. These are missing links. They show a transition from chimp to human. Fossils have also been found showing links of reptile to mammal, reptile to bird, fish to amphibian etc.
jshealy Says:
This is too easy. You haven't proved anything except being insulting. I won't stoop to your level. Now who's truly "evolved?" You haven't even refuted the original argument I've started above. Remember-missing links? They don't exist. Never been found. Pitiful indeed.
dman519 Says:
You know how we think back on people from 500 years ago who believed that rainbows were miracles and the earth was the center of the universe and we think "Man, those people were so ignorant." Well, 500 years from now people will look back on people like you with the same pity.
jshealy Says:
Theory-A supposition or a system of ideas intended to explain something, esp. one based on general principles independent of the thing to be...: "Darwin's theory of evolution" In other words, a good guess. It HASN'T been proven. No matter how much you've been indoctrinated.
dman519 Says:
You've taught science yet you don't even know the definition of "theory". Theory is a word that is thrown around a lot nowadays by layman and is used to mean "a guess". In the scientific community, the word "theory" means fact. Evolution CAN be proven and it has been. There is more evidence out there for it than you could even possibly imagine and from DIFFERENT scientific disciplines. Geology, comparative anatomy, genetics, embryology, etc.
