Married man

Marriage requires a lot from a man if he wants a happy marriage: he'll have to put his wife and children before himself most of the time. He'll probably work more, spend less time with his friends, and stay faithful. 

But research clearly shows that, generally speaking, it will be well worth it. Two professors published a report based on studies of the costs and benefits of marriage to men. "They found a clear takeaway: Marriage is good for men in “every conceivable measure.”

Benefits include more happiness, less depression, more wealth accumulation, and they even eat "more fruits and vegetables":

"Men who get and stay married live almost 10 years longer than their unmarried or divorced peers. Married men eat more fruits and vegetables. Married men also appear to manage illness better, with their wives providing companionship and advocating on their behalf with doctors and nurses. A recent Harvard study found married men diagnosed with cancer live significantly longer."
