I can think of one more reason, that is because "we can".  It is not about purely physical joy anymore when we go out to have fun.  I think for most of us, spending extra bucks in SN is not an issue nor a worry, it becomes clear to us that because we can, this sense of power and control (that we can "Cover the Sky when Crossing the Ocean !") is the excitment behind the fun.  I sometimes argue with wife on how to raise the kids as I tend to spoil them with toys as long as they are not too expensive and violent.  THis is because when I was a kid, my family was poor and cannot spoil me like that.  Now that I can, I feel happy to be able to spoil my kids, the same way that I can have some fun without ruining the family.  I guess as ong as you can draw the line there that there are things you won't even contemplate wihile having fun, you are at least trying to protect your family.  But at the, we all know we are making excuses to justify our action !

Totally agree !  I think this is a good way by which we can be "devil" in a confined environemnt, much rather than becoming a real devil.  There is no such thing as a Mr. Total Good Man !

The problem with us, Man, is that we are all physical animals.  We are easily stimulated by physical objects, sport cars, pretty faces etc.  Sometimes, our mind drifts around our body moving from the top to the lower end, and that dictates our action, and women just cannot understand !
