David Andrew Farrow (born January 10, 1975) is a two-time Canadian Guinness World Record Holder for Most Decks of Playing Cards Memorized in a Single Sighting, entrepreneur, memory coach, speed reader and keynote speaker. He is best known for winning the Guinness World Records for Most Decks of Playing Cards Memorized in a Single Sighting in 1996 and again in 2007 when he set out to reclaim his record after it was beaten in 2002. The initial record was set at the Guinness World Records museum in Niagara Falls, Ontario, Canada while the latter was performed for Discovery Channel Canada at CTV Television Network studios. Both records were accomplished under the controlled supervision of multiple cameras and multiple independent witnesses. Early life Dave Farrow was born on January 10, 1975, in Kitchener, Ontario, to Wayne and Virginia Farrow. Born into a blue-collar family, his father Wayne is a retired factory worker, who dealt in space shuttle parts and his mother Virginia is a homemaker. After resuscitating him twice during birth, doctors offered a bleak prognosis, suggesting Farrow was unlikely to survive past his first year due to the numerous health problems that would plague his infancy and childhood. He was constantly in and out of the hospital during his formative years, which affected his studies and severely impacted his learning. Despite experiencing this setback, Farrow was able to catch up on schoolwork through independent study. Although he went beyond the curriculum coursework and completed the requirements for the following year, the school refused his request to skip a grade. Farrow eventually got bored and started skipping school. His truancy coupled with his medical issues started to play a toll on his academia and by middle school; he fell behind the learning curve. He was told by one of his teachers that would not amount to anything in life and that he would end up in the blue-collar industry like his father. In addition, Farrow was diagnosed with attention deficit hyperactivity disorder (ADHD) and dyslexia. The doctors recommended that he be put on a consistent course of Ritalin but his mother refused. Following this decision, Farrow decided to take matter into his own hands and began exploring behavior modification approaches to manage his disability. He started going to the library on a frequent basis to expand his knowledge and coming up with memory methods to combat his ADHD and dyslexia through
