Don told me he could not sleep long as in young days. He got up in 4 hours after falling asleep at night. Then he would go on being awake for 2 or 3 hours until he feels sleepy again and takes 2 or 3 hours sleep again. In the meantime, he often shows up on 40m in our sunset time. I told him how to fall asleep. It is the autonomic training method famous for a treatment for insomnia. Surprisingly, he answered to me he had remebered that since I taught him that 2 years ago. What a shame! I have totally forgot telling that to him before. He told me he had practised that method which worked out fine for him. I didn't dare to ask him if he had not tried that yesterday yet. Anyway, that sleep pattern is quite normal for our age. Wishing him good sweet dream, I gave him 73.
I was stunned to know that I had repeated the same thing to the other in QSOs without being conscious of it at all. Of course, aged people often do that. I could accept it without any problem. But it is a bit embarrassing that it has happened to me. I have realized that I was already in the old age. I should be careful about that. But I could not avoid it at all. I should ask friends for making such a trouble to them. Don was kind enough to emphasize that that method had been helpful to him but not that I used to tell the same thing before.
