I have noticed with other people in the past, that a limp is a hard habit to get out of. When you have an injury and begin to favor one limb, you kinda train yourself to do it, and it becomes sub-conscious. When healing occurs, the limp stays, although no longer necessary. I am not a doctor, nor do I play one on televesion. Heck, I didn't even stay at a Holiday Inn Express last night. Just something I have observed in human behavior.
