Is it possible for the man to get sick when the woman is pregnant?

I don't know about anyone else but I had three months of morning sickness with both of my children and felt the labor pains both times my wife gave birth. At one point I was outside of the hospital in the parking lot with my mother and my wife was 7 stories above us and I still felt every labor pain! I believe but do not have any data to support it that "sympathy pains or sickness" is deppendant on the strength of the bond between you and your loved one.
