Context: Wayne's World 2, while retaining Wayne Campbell, Garth Algar, and Wayne's girlfriend Cassandra Wong, has a much more serious tone and outcome than the first Wayne's World movie. The movie opens with Wayne explaining that the course of the 'past year,' in this case the year between the two movies, has seen a lot of changes in his life. Although he still hosts his television show Wayne's World, he now lives in an apartment building which was once a doll factory. He is very proud of the fact that Cassandra's carrer is taking off and they are still very involved with each other, but talks about how people are telling him he needs to find focus in his life and 'grow up.' In a dream, Wayne sees singer Jim Morrison, who tells Wayne to put on a music festival in Aurora, Illinois. The festival itself makes Wayne go through the process of booking bands and getting permits for the event, although the event itself isn't truly the core to the story. The festival takes a back seat to Wayne's romance with Cassandra, who he comes to acknowledge he truly loves and wonders about their future together. Wayne, about half way through the film, has to prove himself to Mister Wong, Cassandra's father. In a satire of classic Kung Fu movies, Wayne and Mister Wong battle each other while dubbing themselves. Wayne proves himself to be a worthy warrior, but does not earn the complete respect of Mister Wong. Cassandra's carrer now centers around her producer, Bobby Kahn, played by actor Christpher Walken. Wayne is suspiscious of Cassandra and Bobby's relationship together, as it becomes obvious to Wayne that it sees that where ever Cassandra is Bobby is also. Wayne spies on Cassandra and later confronts her about what he witnessed, causing her to punch him in the face and seeminly ending their relationship. Wayne struggles with this throughout the rest of the movie, wanting to make peace with Cassandra and win her back. Wayne later discovers that Cassandra is about to be wed to Bobby, forcing Wayne to abandon his post on the day of his festival to stop the wedding and pronounce his love for Cassandra. At the very last minute, he interupts the wedding ceremony of Cassandra and Bobby, where he then discovers that Mister Wong had set up the wedding to gain his green card. Wayne and Cassandra then return to Wayne's music festival where she performs and Aerosmith arrives shortly thereafter. The movie ends immediately after the festival, leaving the viewer to believe that Wayne has finally 'grown up' into an 'adult' now that he has not only confirmed his love for Cassandra but managed to organize and run a music festival without forgetting what it means to 'have fun.' Garth becomes involved with a seemingly older woman in Wayne's World 2, who he later discovers is married and hisentiore relatinship with the woman was a sham to get back at her husband, who she wants dead. Garth's character hasn't seem to have grown or changed much from the first Wayne's World movie, however by the end of Wayne's World 2 it appears as if he has matured emotionally to where Wayne's character was at the end of the first Wayne's World movie, although his character and his problems never appear to have found resolution by the end of Wayne's World 2.
Question: What do Wayne Campbell and Garth Algar call their concert?

Context: In the Caucasus region of Russia, nearly 50 out of every 100,000 people live to celebrate their 100th birthday, and many don't stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Russian old people aren't alone. The Pakistanis, who live high in the Himalaya Mountains, and the Ecuadorans of the Andes Mountains seem to share the secret of long life, too. These people remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked "at what age does youth end?"most of these old people had no answer. Several replied, "Well, perhaps at age 80." What accounts for this ability to survive to such old age, and to survive so well?First of all, hard physical work is a way of life for all of these long-lived people. They begin their long days of physical labor as children and never seem to stop. For example, Mr . Rustam Mamedov is 142 years of age. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intention of retiring from his life as a farmer. "Why?What else would I do?"he asks. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 1,660 to 1,000 meters above sea level. The air has less oxygen and is pollution-free. This reduced-oxygen environment makes the heart and blood vessel system stronger. Another factor that may contribute to the good health of these people is their isolation. To a great extent, they are separated from the pressures and worries of industrial society. Inherited factors also play some role. Most of the longest-lived people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.
Question: What is the main way of life for all of these long-lived people?

Ex Output:
hard physical work.
