 Solid Fire Pits is just one of the 5 million U.S. businesses that rely on TikTok every day. TikTok sparks business. Here's NASCAR Hall of Famer Mark Martin. As a race car driver for 40 years, I survived a lot of crashes. Not everyone can run into a wall at 200 miles an hour and walk away. Without a seat belt, I wouldn't be alive today. Now I'm retired, back home in Arkansas driving my pickup. I'm shocked how many people aren't wearing seat belts. Why risk your life when it only takes two seconds to buckle up?
