I have great thanks for the foods, food services and transportation, too. Very few of us could produce enough food to survive.
I'm also very grateful this old body works as well as it does. Whoever coined the phrase, "Youth is wasted on the young," really knew what they were talking about. Good health is so often taken for granted, and by those who are fortunate enough to have it.
However, the thing I'm MOST grateful for (and when I talk about it, a lot of people look at me like I've got 3 heads), is that consciousness survives physical death. The evidence is overwhelming.
I'm looking forward to making my transition into non-physical reality, whenever that might happen. Anytime is fine with me.
