At 45 years old, it's strange to think that we haven't seen Kasey Kahne behind the wheel of a NASCAR stock car in nearly seven years. A veteran of over 500 Cup races with an impressive 18 wins, Kahne's NASCAR career came to an abrupt end in the middle of the 2018 season.
Kahne stepped out of the car after struggling with heat exhaustion over the course of the three to four-hour races, facing an out-of-control heart rate and an inability for his body to regulate its internal temperature. The slender and well-trained Kahne was in shape, but no matter what he did, he could not combat the extreme dehydration, and it was only getting worse. There was a fear of passing out while behind the wheel, or even suffering heat stroke if he continued.
