Why does everyone relate it to SEX only? Can\'t it happen the moment (1) someone cracks a wonderful joke (2) Musharraf meets Vajpayee

(3) a kid finds his lost ball (4) you find your exam results (5) you look at a newborn (6) a girl proposes a boy (7) you win a lottery (8) you come across a cute little puppy in the rain, etc.<br><br>
I feel that irrespective of age the so-called ‘thing’ happens to every one, and always… What do you guys think about it?
