One Whack Jack is history. As I have stated before, I actually watch auto racing for the racing, not the crashes. Jack Sprague has caused a ton of crashes this year and I am so happy that this menace is off the track. Hopefully one of the more desperate teams will not try to "rehab" him. The only bad part about this is that he will probably go back to the Busch or Truck series and cause more trouble. Unless he goes to the 12 team of Terry Bradshaw. They let Kerry Earnhardt go after he crashed yet another car. Even Jack don't drive as bad as "Not Junior."
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
