Some context: Kulwicki grew up in Greenfield, Wisconsin, a suburb of Milwaukee known for its Polish-American neighborhoods, near the Milwaukee Mile racetrack. After his mother died, his family moved in with his grandmother, who died when Kulwicki was in seventh grade. A year later, his only brother died of a hemophilia-related illness. Kulwicki attended Pius XI High School, a Roman Catholic high school in Milwaukee, and received a bachelor of science degree in mechanical engineering from the University of Wisconsin-Milwaukee in 1977.
Kulwicki began his racing career as a 13-year-old kart racer. His father built engines as the crew chief for Norm Nelson and Roger McCluskey's United States Automobile Club (USAC) racecars. Because his work involved travel, Kulwicki's father was unable to help his son at most kart races, so Kulwicki's resourcefulness was often tested trying to find someone to transport his kart to the track. Even when Kulwicki asked his father for advice, he typically ended up doing most of the work himself. "I showed him how", Gerry Kulwicki said. "And he said: 'Why don't you do it? You can do it better.' And I said, 'Well, if you do it for a while, you can do it better.'"  Many local-level American racetracks host their own season championships. In Wisconsin, numerous locations held dirt and asphalt short track racing. Kulwicki started driving stock cars at the local level at the Hales Corners Speedway and Cedarburg Speedway dirt oval tracks. In 1973, he won the rookie of the year award at Hales Corners Speedway in the Milwaukee suburb of Franklin, and the next year started racing late models - the fastest and most complicated type of stock cars raced at the local level - at the same track. That season, he won his first feature race, at Leo's Speedway in Oshkosh.  Kulwicki moved from dirt tracks to paved tracks in 1977. He also teamed up with racecar builder Greg Krieger to research, model, engineer, and construct an innovative car with far more torsional stiffness than other late models. The increased stiffness allowed the car to handle better in the corners, which increased its speed. Racing at Slinger Super Speedway, he won the track championship in 1977. In 1978, Kulwicki returned to Slinger; that same year he started racing a late model at Wisconsin International Raceway (WIR), finishing third in points in his rookie season at the track. In 1979 and 1980, he won the WIR late model track championships.  In 1979, Kulwicki began competing in regional to national level events sanctioned by the USAC Stock Car series and the American Speed Association (ASA), while remaining an amateur racer through 1980. When Kulwicki raced against future NASCAR champion Rusty Wallace in the ASA series, the two became friends. Kulwicki's highest finish in the ASA season points championship was third place, which he accomplished in both 1982 and 1985, with five career victories and twelve pole positions.
Was he able to race cars at such a young age?
A: Kulwicki began his racing career as a 13-year-old kart racer.

Some context: John Owen Brennan (born September 22, 1955) was the Director of the Central Intelligence Agency (CIA) from March 2013 to January 2017. He served as chief counterterrorism advisor to U.S. President Barack Obama; his title was Deputy National Security Advisor for Homeland Security and Counterterrorism, and Assistant to the President. His responsibilities included overseeing plans to protect the country from terrorism and respond to natural disasters, and he met with the President daily. Previously, he advised President Obama on foreign policy and intelligence issues during the 2008 presidential campaign and transition.
In late 2008, Brennan was reportedly the top choice to become the next Director of the CIA in the incoming Obama administration. However, Brennan withdrew his name from consideration because of opposition to his CIA service under President George W. Bush and past public statements he had made in support of enhanced interrogation and the transfer of terrorism suspects to countries where they might be tortured (extraordinary rendition). President Obama then appointed him to be his Deputy National Security Advisor for Homeland Security and Counterterrorism, the President's chief counterterrorism advisor and a position that did not require Senate confirmation.  In August 2009, Brennan criticized some Bush-administration anti-terror policies, saying that waterboarding had threatened national security by increasing the recruitment of terrorists and decreasing the willingness of other nations to cooperate with the U.S. He also described the Obama administration's focus as being on "extremists" and not "jihadists". He said that using the second term, which means one who is struggling for a holy goal, gives "these murderers the religious legitimacy they desperately seek" and suggests the US is at war with the religion of Islam.  In an early December 2009 interview with the Bergen Record, Brennan remarked, "the U.S. intelligence and law enforcement communities have to bat 1.000 every day. The terrorists are trying to be successful just once". At a press conference days after the failed Christmas Day bomb attack on Northwest Airlines Flight 253 by Umar Farouk Abdulmutallab, Brennan said U.S. intelligence agencies did not miss any signs that could have prevented the attempt but later said he had let the President down by underestimating a small group of Yemeni terrorists and not connecting them to the attempted bomber. Within two weeks after the incident, however, he produced a report highly critical of the performance of U.S. intelligence agencies, concluding that their focus on terrorist attempts aimed at U.S. soil was inadequate. In February 2010, he claimed on Meet the Press that he was tired of Republican lawmakers using national security issues as political footballs, and making allegations where they did not know the facts.  Brennan was present in the Situation Room in May 2011 when the United States conducted the military operation that killed Osama bin Laden. He called President Obama's decision to go forward with the mission one of the "gutsiest calls of any president in memory." In the aftermath of the operation, Brennan said that the U.S. troops in the raid had been "met with a great deal of resistance," and bin Laden had used a woman as a human shield.
