What is sterling marlin health?

As an AI language model, I don't have access to the latest updates or information on Sterling Marlin's current health status. However, in 2012, Sterling Marlin underwent surgery to remove a health concern from his spinal cord. Later, it was revealed that Marlin experienced vertigo as a result of the surgery and was forced to retire from racing due to his health. Marlin has since recovered from his surgery and has made appearances in the NASCAR world. However, there is no information on his current health status.
