I feel that way more often than not these days, DrPaulLee. Not that I'm suicidal but, that I have nothing more to contribute. Certainly nothing that will change the world. But, when you live to be as old as I am or older, you know from experience, that life has a way of smacking you right in the face and changing the world as you know it in an instant. You don't even have to get out of the lazy boy recliner. Life is short. Your time will come. There is no need to shorten it.
