Problem: Yelberton Abraham Tittle Jr. (October 24, 1926 - October 8, 2017), better known as Y. A. Tittle, was a professional American football quarterback. He played in the National Football League (NFL) for the San Francisco 49ers, New York Giants, and Baltimore Colts, after spending two seasons with the Colts in the All-America Football Conference (AAFC). Known for his competitiveness, leadership, and striking profile, Tittle was the centerpiece of several prolific offenses throughout his seventeen-year professional career from 1948 to 1964. Tittle played college football for Louisiana State University, where he was a two-time All-Southeastern Conference (SEC) quarterback for the LSU Tigers football team.

A photo of a dazed Tittle in the end zone taken by Morris Berman of the Pittsburgh Post-Gazette on September 20, 1964, is regarded among the most iconic images in the history of American sports and journalism. Tittle, in his 17th and final season, was photographed helmet-less, bloodied and kneeling immediately after having been knocked to the ground by John Baker of the Pittsburgh Steelers and throwing an interception that was returned for a touchdown at the old Pitt Stadium. He suffered a concussion and cracked sternum on the play, but went on to play the rest of the season. Post-Gazette editors declined to publish the photo, looking for "action shots" instead, but Berman entered the image into contests where it took on a life of its own, winning a National Headliner Award. The photo was published in the October 2, 1964, issue of Life magazine. It is regarded as having changed the way that photographers look at sports, having shown the power of capturing a moment of reaction. It became one of three photos to hang in the lobby of the National Press Photographers Association headquarters, alongside Raising the Flag on Iwo Jima and the Hindenburg disaster. A copy now hangs in the Pro Football Hall of Fame. After at first having failed to see the appeal of the image, Tittle eventually grew to embrace it, putting it on the back cover of his 2009 autobiography. "That was the end of the road," he told the Los Angeles Times in 2008. "It was the end of my dream. It was over." Pittsburgh player John Baker, who hit Tittle right before the picture was taken, ran for sheriff in his native Wake County, North Carolina in 1978, and used the photo as a campaign tool. He was elected and went on to serve for 24 years. Tittle also held a fundraiser to assist Baker in his bid for a fourth term in 1989.

Are there any more interesting information about the famous photo?

Question:
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".
