Old Man Walks the Earth

ANCHOR: Harry Lee McGinnis claims the secret to living longer is to go see the world. He’s preparing for the final stage of an 80000-mile around-the-world walk. Here’s his story. STORY: Harry Lee McGinnis could easily pass for 60 – he is, in fact, pushing 81. His secret? Never keeping still; a wander lust that impelled the American to set off on foot around the world. That was 18-years ago. [Harry Lee McGinnis, Walking the World]: “You want to live longer, go out and see the world. When you retire, don’t sit in front of the TV set and gain 20 or 50 pounds and drink the beer and eat the sandwiches and can hardly get out of the chair. Go see the world!” His epic journey began in Dublin on St Patrick’s Day 1992. Continental Europe, Africa, Asia and South America followed. The former World War II army sniper has now reached Panama City and over the course of the next five years McGinnis will complete his global odyssey through Central America before eventually returning home to the United States. [Harry Lee McGinnis, Walking the World]: “I’ve seen 70 of the largest capitals, largest land masses and I’m always asked, well ‘aren’t you finally getting tired?’ How can you be tired when everyday you don’t know what’s around the corner.” Fans can chart his progress on his Web site, www.hawkwalk.com, which describes how he camps out along roadsides as well as some of the scrapes he’s got into along the way, including brushes with knife-wielding assailants in north Africa.

This is a show NOT TO BE MISSED. SHOW SYNOPSIS: TRIASSIC PERIOD 245 to 208 million years ago Roughly 248 million years ago (mya), the Permo-Triassic extinction occurred. This is the largest extinction known. About 95% of all species and about 60% of the genera died out, including many marine animals (like the trilobite). The cause of the Permian extinction might have been global cooling, volcanic eruptions, or a decrease in the continental shelf area during the formation of the giant continent, Pangaea. This catastrophic extinction and continental rearrangement opened the way for the rise of the dinosaurs and mammals. There were no dinosaurs at the beginning of the Triassic, but there were many amphibians and some reptiles and dicynodonts (like Lystrosaurus). During the early Triassic, corals appeared and ammonites recovered. The Triassic meadows and prairies would have been covered in ferns, low cycads, club mosses and horsetails as these plants dominated the land; in the Northern hemisphere, conifers flourished. There was no grass and no flowers. The first half of the Triassic was dry and highly seasonal, with particularly large annual temperature variations in the vast continental interior of Pangaea. Low sea levels probably exaggerated these temperature extremes. The environment was harsh, with deserts and dry wilderness. 230 million years ago a unique breed of reptile appears, the dinosaur. Most Triassic dinosaurs were small bipeds, but at the end of the Triassic the …
