Woods overcame difficulties with stuttering as a boy. This was not known until he wrote a letter to a boy who contemplated suicide. Woods wrote, "I know what it's like to be different and to sometimes not fit in. I also stuttered as a child and I would talk to my dog and he would sit there and listen until he fell asleep. I also took a class for two years to help me, and I finally learned to stop."
Woods was severely myopic; his eyesight had a rating of 11 diopters. In order to correct this problem, he underwent successful laser eye surgery in 1999, and he immediately resumed winning tour events. (He received money from TLC Laser Eye Centers to endorse them, In 2007, his vision again began to deteriorate, and he underwent laser eye surgery a second time.)
Woods had back surgery on September 16, 2015. In late March 2016, he announced that he would miss the Masters while he recovered from the surgery; he had also missed the 2014 Masters due to a back problem. "I'm absolutely making progress, and I'm really happy with how far I've come," he explained in a statement. "But I still have no timetable to return to competitive golf." However, he did attend the Masters Champions Dinner on April 5, 2016. For the first time in his career, he missed all four majors in one year due to problems with his back. In October 2016, he told Charlie Rose on PBS that he still wanted to break Jack Nicklaus's record of 18 major titles. Woods underwent back surgery in December 2016 and spent the next 15 months off the Tour. He made his return to competitive golf in the Hero World Challenge.
In 2002, Woods was involved in every aspect of the launch of Buick's Rendezvous SUV. A company spokesman stated that Buick was happy with the value of Woods' endorsement, pointing out that more than 130,000 Rendezvous vehicles were sold in 2002 and 2003. "That exceeded our forecasts," he was quoted as saying, "It has to be in recognition of Tiger." In February 2004, Buick renewed Woods' endorsement contract for another five years, in a deal reportedly worth $40 million.
At a hearing on October 27, 2017, Woods pleaded guilty to reckless driving. He received a year of probation, was fined $250, and ordered to undergo 50 hours of community service along with regular drug tests. He was not allowed to drink alcohol during the probation, and if he violated the probation he would be sentenced to 90 days in jail with an additional $500 fine.
Surgery: Pulled out of next two PGA TOUR starts, the Genesis Open and The Honda Classic. Released statement: "My doctors have advised me not to play the next two weeks, to continue my treatment and to let my back calm down. This is not what I was hoping for or expecting. I am extremely disappointed to miss the Genesis Open, a tournament that benefits my foundation, and The Honda Classic, my hometown event. I would like to thank Genesis for their support, and I know we will have an outstanding week." In April, announced on his website he had undergone further back surgery. The operation was performed by Dr. Richard Guyer of the Center for Disc Replacement at the Texas Back Institute.
