IN: Hans Lundgren was born on 3 November 1957 in Spanga, the son of Sigrid Birgitta (nee Tjerneld), a language teacher, and Karl Johan Hugo Lundgren, an engineer and economist for the Swedish government. He lived in Spanga until the age of 13, when he moved to his grandparents' home in Nyland, Angermanland. Some sources wrongly state 1959 as his year of birth, but Lundgren himself has confirmed it to be 1957. He has two sisters and an older brother; he was raised in the Lutheran church.

Although Lundgren has never competed as a professional bodybuilder, he has been closely associated with bodybuilding and fitness since his role as Drago in the mid-1980s. Bodybuilding.com said, "Looking like a man in his 30s rather than his 50s, Lundgren is the poster boy of precise nutrition, supplementation and exercise application that he has practiced for over 35 years." In an interview with them, he claimed to often train up to six days a week, usually one-hour sessions completed in the morning, saying that "it's just one hour a day, and then you can enjoy the other 23 hours". Although he had begun lifting weights as a teenager, he cites co-star Sylvester Stallone as the man who got him into serious bodybuilding for a period in the 1980s after he arrived in the U.S. Stallone had a lasting influence on his fitness regime and diet, ensuring that he ate a much higher percentage of protein and split his food intake between five or six smaller meals a day. Lundgren has professed never to have been "super strong", saying that, "I'm too tall and my arms are long. I think back then [Rocky IV] I was working with around 300 pounds on the bench and squat." In a January 2011 interview with GQ he announced he is working on releasing his own range of vitamins and supplements. He wrote an autobiographical fitness book, Train Like an Action Hero: Be Fit Forever, published in Sweden (by Bonnier Fakta) on 9 August 2011, offering tips he learned over the years to work out in various situations (with a busy schedule and a lot of traveling). On 9 September 2014, Lundgren published Dolph Lundgren: Train Like an Action Hero: Be Fit Forever, a book which contains a detailed account of his earlier life and troubles. He cites a better quality of life as having inspired him to maintain his physical fitness. When in Los Angeles he trains at the Equinox Gym in Westwood and when at home in Marbella, Spain, he trains at the Qi Sport Gym in Puerto Banus. Dolph does, however, also like to spar and practice his karate in the gym to keep in top shape aside from weight lifting. He cites dead lifting and squats as the best exercises for muscle building. Lundgren is not a heavy drinker, but has professed on many occasions to being fond of tequila and cocktails, citing his knowledge in chemical engineering as "making really good drinks".

So there is no more information about his training or diet?

OUT: he cites co-star Sylvester Stallone as the man who got him into serious bodybuilding for a period in the 1980s after he arrived in the U.S.

IN: Fazlur Rahman Khan (Bengali: phjlur rhmaan khaan, Fozlur Rohman Khan) (3 April 1929 - 27 March 1982) was a Bangladeshi-American structural engineer and architect, who initiated important structural systems for skyscrapers. Considered the "father of tubular designs" for high-rises, Khan was also a pioneer in computer-aided design (CAD). He was the designer of the Sears Tower, since renamed Willis Tower, the tallest building in the world from 1973 until 1998, and the 100-story John Hancock Center. Khan, more than any other individual, ushered in a renaissance in skyscraper construction during the second half of the 20th century.

Khan's central innovation in skyscraper design and construction was the idea of the "tube" structural system for tall buildings, including the framed tube, trussed tube, and bundled tube variants. His "tube concept", using all the exterior wall perimeter structure of a building to simulate a thin-walled tube, revolutionized tall building design. Most buildings over 40 stories constructed since the 1960s now use a tube design derived from Khan's structural engineering principles. Lateral loads (horizontal forces) such as wind forces, seismic forces, etc., begin to dominate the structural system and take on increasing importance in the overall building system as the building height increases. Wind forces become very substantial, and forces caused by earthquakes, etc. are important as well. The tubular designs resist such forces for tall buildings. Tube structures are stiff and have significant advantages over other framing systems. They not only make the buildings structurally stronger and more efficient, but also significantly reduce the structural material requirements. The reduction of material makes the buildings economically more efficient and reduces environmental impact. The tubular designs enable buildings to reach even greater heights. Tubular systems allow greater interior space and further enable buildings to take on various shapes, offering added freedom to architects. These new designs opened an economic door for contractors, engineers, architects, and investors, providing vast amounts of real estate space on minimal plots of land. Khan was among a group of engineers who encouraged a rebirth in skyscraper construction after a hiatus of over thirty years. The tubular systems have yet to reach their limit when it comes to height. Another important feature of the tubular systems is that buildings can be constructed using steel or reinforced concrete, or a composite of the two, to reach greater heights. Khan pioneered the use of lightweight concrete for high-rise buildings, at a time when reinforced concrete was used for mostly low-rise construction of only a few stories in height. Most of Khan's designs were conceived considering pre-fabrication and repetition of components so projects could be quickly built with minimal errors. The population explosion, starting with the baby boom of the 1950s, created widespread concern about the amount of available living space, which Khan solved by building upward. More than any other 20th-century engineer, Fazlur Rahman Khan made it possible for people to live and work in "cities in the sky." Mark Sarkisian (Director of Structural and Seismic Engineering at Skidmore, Owings & Merrill) said, "Khan was a visionary who transformed skyscrapers into sky cities while staying firmly grounded in the fundamentals of engineering."

Does this system help when the building collapse?
