In the US there is an expression, "The grass is always greener on the other side of the fence." Juliana's answer seems to parallel this. When you are single you would like to be married, but when you are married you may want to be single again. What I can say is that research shows that married men live longer than single men.

It all depends how you want to spend your life & how you foresee your old age. Who'll look after you when you are a pensioner?

Hm... on the one hand, I would like to be married, on the other hand... it's so good when you're just by yourself and do not have to submit your will with somebody else's...

Today isn't necessary to get married to live with someone. The marriage it's just a contract. So, if the question is live alone or with somebody, this depends if you find or not the right person.

Well, married people wanna live alone and single ones wanna get married...
