Old enough to remember that the world was supposed to be frozen solid by now & that most of us were supposed to have starved to death by now. Old enough that my first 3 kids were all over the horrible issues with styrofoam killing the environment and the plastic rings from can holders killing animals and birds. Now my youngest is being taught that plastic bottles are killing the environment, and oil and windmills are killing the earth, all animals, and birds, and that this current slight rebound from the foretold Ice Age means that the entire world will soon cook to death and we'll all starve. 
Too dam old to dance the hoochi-choochie but still young enough to wish I could. Not easy climbing up on the bar with a lamp shade on my head anymore.
Too old to stay awake long enough in a bar to pick up a one night stand, for me it would be a one night lean.
Too old to be able to eat anything and stay at 100 pounds.
Young enough to to still have one parent alive, watch my kids and their kids grow up in whatever their world is like today.
Young enough to become interested in the hobby's of others from sky diving to rock collecting.
Still Young enough to be able when the time comes to see the Nympho is wearing no clothes.
