and he says to him you are god, you are perfect and george burns says i'm not perfect and he said it wasn't perfect and he says as god the avocado. i made the pitch to big. the reason the avocado has the pit that seems too big is because that was eaten by ground sloths that would carry them miles and miles through the forest and these powerful digestive juices would prepare the seat to be deposited elsewhere. this is a tree in central park, honey locust trees covered with fornes. there's no reason for a tree like that to have fornes except dustin bonds used to feed on those trees and go for the pond and the trees to put up a defense against getting the low work and limbs even. so they have been fornes to protect them from the mastodons. the search for the missing toomas. thar darwin found these long tubes in a certain orchid found a madagascar are and he said there has to be a malkoff or some kind of insect with a tongue 14 inches long that can get in there to get the nectar and this pollinates the plant by carrying the nectar and entomologists told him that's ridiculous, that is

that and george burns as i'm not perfect.epare the seats to be deposited elsewhere. this is a tree in central park, a honey locust tree, that's covered with thorns. there's no breezeway treelike that you have thorns, except that in the mastodons used to feed on those trees and go for the pods. the trees had to put up a defense against getting their lower barks and limbs even. so they have thorns still to protect them from the mastodons. search for them missing moth. darwin said, he found the nectarines come these long tubes in a certain orchid found in madagascar. and he says there has to be a model or some kind of insect with a tone 14 inches long that can get in there to get the nectar, and will thus pollinate the play. and at the mall just told him, that's ridiculous, that's impossible, they're so insectlike that. and about, i don't know, 20, 30 years after darwin died, they found the moth. and it was called the moth that was predicted. well, the search for the missing link, of course in darwin's day, everybody, they had h

. >> you remember george burns once said he loved the newshour, he went to sleep to it every night. he may have been watching that piece. i don't really know. but no, it's -- in the culture in general there is a shrinking of the sound bite. . it affects us all. that obviously was tremendously problematic, because if you're talking about explaining something in 1 minute 20 seconds, people here today, we had moments in the panel where as an aside, i would ask somebody a question, and it would take one minute and 20 seconds to have the exchange. that is obviously a problem. >> people are presented with the idea that they did not have to take the argument at 15 or something like that. add to that the willingness of politicians to exploit that, and you end up with situations like we have the summer with health care. people do not seem that willing to read, for instance. we had a lot of people pay attention to who should, but frankly do not. >> some people that you're talking by read a great deal. it is not their unwillingness to read, it is what they are reading. >> it is the idea that e

george mason university. just a question primary to jennifer burns. i met your book and i found the majority of it persuasive. one area wasn't i was a persuaded your contention that it was ayn rand support for capitalism which prevented sort of a libertarian leftist alliance. it seemed to me to take support for capitalism. another factor is on the sure there was much edges on the left in this kind of coalition. so i wonder if you could elaborate on that further. and also, am i wrong, was there some genuine interest in the left in the '70s and in particular what are people on the left, were they making some sort of concession to libertarians to make the lifework? >> so i do think that capitalism, commitment to markets remained this fundamental stumbling block. rothbard was more willing than rand to say let's kind of put that aside and attack the state that he was focused on state power. he was in an artist. and whatever way you could attack the state was welcome to him. i think in a lot of history about libertarianism, rothbard, mr. libertarian and. i

george washington university. he says most people overestimate the number of calories they burn during a workout and then tend to overeat afterwards. >> by restricting your diet, you can easily cut out 1,500 calories, but to get that amount of exercise in to burn that amount of calories, it takes much more. >> reporter: exercise also boosts your metabolism, so after a vigorous exercise, some might be starving and then lose track of how many calories they're putting away when they eat. >> where it really hits me in the morning is i end up ravenous. >> reporter: but others say it's merely a matter of perception. many say exercising gives them the freedom to eat when they want, so spending an hour at the gym justifies eating pizza for lunch or a greasy burger for dinner. dr. robin says she sees it all the time. >> people feel like it's a carte blanche. i exercised, therefore i can have whatever i want and i don't even have to think about the exercise. >> there are definitely times when i think, i did this, this, and this today so i can have that pizza andake and not feel bad about it. >> reporter: while exercise alone migh

george mason university. this is a question aimed primarily for jennifer burns. i read your book and i found a majority of extremely persuasive one area i was not entirely persuaded was your contention that it was ayn rand's support for katulis and that prevented a libertarian leftist alliance and it is support for capitalism that caused this almost all libertarians had this defining characteristic including those like rauf barb who wanted to have the alliance with the left, he was actually even more opposed to the government regulation than rand was and another factor here also is i'm not sure there was overarch interest on the left in this kind of coalition so i wonder if you could elaborate on that further and am on a long? was there a genuine interest in this on the left in the 70's? and in particular what are people on the left willing to make some sort of concession to the libertarians to make the alliance work? >> so, i do think that capitalism commitment to markets remain fundamental stumbling block. rothbardt was more willing to than rand. he was focused

as henry thorough, george perkins, and john muir who worked tirelessly to protect our collective natural history in such a way it would live on for generations. as noted by ken burns when discussing the need to document the national park system, the chronicle of america's park isn't a mere celebration of our nation's natural treasures but also a story of our people, of the force that is helped shape our lands, and the influence that is will guide our children. the siting to designated as the castle nugent national historic site continues to be heralded as one of the last pristine areas in the region. without hesitation i can attest to the fact that the castle nugent farm is worthy of preservation, worthy of inclusion into the national park system, and truly worthy of being shared as more than just a beachfront property. in the caribbean. but instead is a valuable chapter in our nation's official record of the american story. the national park service testified as such in november at the subcommittee hearing. h.r. 3726 calls for the preservation of 2,900 acres which include caribbean dry forest, sea turtle northwesting areas, large and healthy french coral reefs, a
