Lots of people love going to Disneyland, but few enjoy the experience as much as Jeff Reitz, who has been visiting Disney resorts every day, for the last 2,000 days.
Jeff started his daily visits to the Disneyland Resort in Anaheim on Jan. 1, 2012, after receiving an annual pass as a gift, and hasn't skipped a day since. He was unemployed at the time, and visiting the parks gave him something to look forward to every day and kept his spirits up. Jeff managed to secure a stable job since then, but he still makes time for Disneyland, every evening.
Jeff Reitz loves the rides, but he also enjoys the music, communicating with the staff and visitors, and just watching the other visitors.
On Thursday, Jeff walked through the gate for the 2,000th day, setting a new world record for continued visits to Disneyland, and since his annual pass expires in January 2018, he plans to extend his lead even more. He will decide whether he'll renew his pass and continue his daily routine, but whatever he decides to do, "nobody can take that fun away from me".
Visiting Disneyland every day has had a positive impact on his life. He met his girlfriend, Karen, during one of his visits a few years ago. He has an active social life because of it, communicating with both staff and visitors, and even managed to lose 40 pounds by walking around every day.
Jeff has also been the target of criticism from people, who went as far as to call his daily habit a sickness. He says that Disneyland is a place of release, relaxation, and activity, one that has made him a better person all around.
Believe it or not, Jeff has never received any special treatment from Disney for his loyalty. He doesn't get any special treatment from the staff, and doesn't even get invited to take part in special events.

Meet the longest-living vertebrate（脊椎动物）in the world, the Greenland shark.
Found primarily in the very cold waters of the North Atlantic, these slow-swimming sharks can be as big as the largest great whites, reaching up to 21 feet in length. They're among the largest of carnivorous（食肉的）fish, and yet grow perhaps only a centimeter or so a year. Such slow growth yet big size is usually an indicator of a long-lived animal.
“We only expected that the sharks might be very old,” Julius Nielsen, at the University of Copenhagen in Denmark, told NPR in 2016. “But we did not know in advance. And it was, of course, a very big surprise to learn that it was actually the oldest vertebrate animal.”
Imagine being 150 years old before you're ready to have your first child! Imagine being born before the United States was even a reality. For humans-who rarely make it to a century mark—it's difficult to fully understand.
Little is known about Greenland sharks, even basics such as where they give birth or how many of them there are, though researchers at a July 2017 conference at the University of Exeter thought that they may mate in “hidden” Arctic fjords. No one has even witnessed one hunting, though they have been found to have various vertebrate ones in their stomachs such as polar bear, seals, fast-swimming fish and even moose etc.
Given the shark's incredibly long lifespans, scientists are diving into the sea creature's genome, looking for clues. That conference also highlighted the work being done to separate the shark's longevity gene, with complete DNA information gathered from almost 100 sharks, including some born in the 1750s. Finding such a gene could go a long way in explaining why some vertebrates, like humans, have such limited lifespans.
These sharks also serve as swimming history books. Their tissue, bones and DNA could tell us a great deal about the waters of the world from a time before the Industrial Revolution, large-scale commercial fishing and the pronounced ocean pollution we see today.
Check out what it's like to swim with one in this encounter with what is a small and young—and yet to us, still fairly old—Greenland shark.

A.Greenland shark can live as old as humans.

C.Greenland shark can live more than one hundred years.
D.Greenland shark is really the oldest vertebrate in the world.
3.What kind of animals do Greenland sharks prefer?
A.Both polar bear and seal. B.Only fast-swimming fish.
C.Various vertebrate animals. D.Polar bear, moose and fish.
4.What information can we get from the passage?
A.Scientists declare that they have known all about Greenland sharks.
B.Scientists want to get more information from their study on sharks.
C.Scientists consider sharks can only serve as swimming history books.
D.Scientists just want to know why Greenland sharks have a long life.
On Diwali, we were on a vacation in Dubai and having a good time and lots of fun. One day, we were visiting Abu Dhabi, traveling with a few passengers in a bus. At our first stop, we got out to take some pictures. At our second stop, we noticed that we had forgotten our shoulder bag at first stop. The worst part was that our passports, visas, hotel booking papers, itinerary…everything was inside that bag and we were very panicky, as we had to return to India in 2 days.
During this process of searching for our bags we came into contact with so many strangers whom we found to be really concerned and helpful with our situation.
The tour guide and the bus driver helped us to locate a cab so that we could travel back the first destination to find our bag.
The cab driver helped us in so many ways. He gave us his mobile phone so that we could contact everyone. He took us to a mosque near the first destination hoping that a cleaner might have found a bag. He took us to the nearest police station and helped us in communication with the policeman, who only spoke Arabic.
A policeman, who searched through everything in the lost and found department.
A local man, who actually found our bag, checked the bag and found a number to the travel agency. He informed them and sent his driver to a common destination from where we could get our bag back.
On that day, there was real panic inside me and I was constantly thinking of what would happen next? How will I find my bag? What will happen to us without our passports and visas? In such a mind set I was not able to say a proper THANK YOU to all those persons who helped us in such challenging situation.
I don't even know their names. I will never be able to forget their faces and their kindness. The world needs more humans like them and I decided to try to become one of them. I salute all those strangers and well-wishes for their acts of kindness.
