I was in a rather bad car accident seven years ago. The driver-side door was pushed all the way to the glove compartment. I was in the driver's seat. They had to use the jaws of life to get me out.
My hip and pelvis were fractured in a number of locations. My knees were injured. The doctors thought at first that I would never walk again. Then they said I would always need a walker. Then I'd always need crutches. Then I'd always need a cane. Or I'd have a permanent limp.
Three-and-a-half months after the accident I was walking on my own two feet with no limp. I still get pain in my hips and knees, and if I ever had to change a tire, I'd probably need help getting back up, but outside of that I'm in great shape.
