I'll give you carefee attitude, which is more on the lines of "naivety." (sp?) Idealism I still have, and except for that darn responsibility thing, along with some aches, this is by far the best time of my life at 40-something.. . If your teen years were your best, then you're doing something wrong now.It is what you make it. I promise you I'm having more fun than I did as a teen. Being 43 rocks for me! . .Barring an unfortunate event, (such as touching the wrong father's kids) you'll only be decrepit at 65 if you abuse your body.
