Two keys to ultimate happiness:

1.A long marriage

2.  A lot of sex...Just not with the same person.Sociologist, Catherine Hakim says she's found the idea of marrying someone and only having sex with them has become antiquated in the Internet age.  Sex is now a LEISURE ACTIVITY, and is becoming less and less connected to real, emotional love.

She says marriage is about passionate feelings, emotional fulfillment, love, and support.  Affairs are about excitement, fantasy, and a refusal to just accept growing old.

So . . . the ultimate happiness comes from combining the best things you get from marriage AND the best things you get from lots of sex with OTHER people.

Her best example are the Scandinavian countries, where more couples have something called "parallel relationships" that's being married but accepting that your spouse is going to have sex with other people.

Almost half of men and one-third of women in Finland apparently have parallel relationships . . . and their divorce rate is lower than the rate in countries where open marriages are taboo, like the U.S. and England.

Call me a prude, or just lazy, but I barely have enough time to dedicate to my family, as it is, I couldn't even think about how to squeeze in an affair, even if I wanted to, which I don't. But it would seem that Tiger Woods should be the happiest MF'er in the world.
