Husband and Wife Being in Same Profession; Is It Healthy for Their Marriage?

Do you think a husband and wife being in the same profession is good for their married life? Especially for very demanding professions like medical doctors, bankers, entertainment artistes, etc.

Personally, before I got married, I decided I was never going to marry a fellow banker. Because I know how hectic our lives can be and how it can affect the kids and home. What is your opinion, guys?

As more and more couples compete in the same job market, is it possible to be in the same line of work, not resent your partner's success and have a happy, working marriage?
