If you were introduced to a random group of white-collar workers and offered $1 million if you could select the happiest person in the group, what kind of person would you pick: A man or a woman? Married or single? Children or no children?

According to a new survey released this month, your odds of winning the cash would increase if you skipped any 40-something, single female professionals and focused on the middle-aged male managers with one child at home and a wife who works part-time. In its Office Pulse survey, Captivate Network, a media solutions company, says its uncovered "profiles of the happiest and unhappiest workers."

And here is the profile of the happiest workers:

• Male

• 39 years old

• Married

• Household income between $150,000 and $200,000

• In a senior management position

• One young child at home

• A wife who works part-time
