In history? Alcohol and tobacco. For now, anyway...
Do you remember all the good times you have had while drunk and smoking? Do you have the experience and skills developed while not drunk or smoking a cigarette?
No memory or something. Live on the edge, avoid tobacco and alcohol? Get the most out of time.
Either forgot or maybe, God wrote it. I often completely forget what I write. Only to read it a little later and find myself amazed that I wrote it. I rarely use the words I write? Make sense?
