Okay I'll admit I borrowed this from a friend but I found it to be so true ~
…With time, people gain weight because we accumulate so much information and wisdom in our heads that when there is no more room, it distributes out to the rest of our bodies. So we aren't heavy, we are enormously cultured, educated and happy. Beginning today, when I look at my butt in the mirror I will think....... ... Good grief, look how smart I am! Must be where the expression 'Smart Ass' comes from!
Personal note: I am oh so wise ~ My cup runneth over!
