The first white man to find Cumberland Falls was Zechariah Green. He and his men were floating down the Cumberland River when they heard ominous noises ahead. They quickly abandoned their boat and swam for shore. From there they watched the boat go over the falls.

We were not nearly so much danger as we walked beside the river, climbing up and down so that we got to see the falls from both the top and the bottom.

Tonight we enjoyed Chinese food at a restaurant where our Strong Son enjoys getting take-out food. The menu gave us the choice of a dinner, which included entrée, rice, egg roll and soup, or “a la carte” which was just the entrée and rice. My husband, DD, and I all ordered a la carte, and had more than enough food. SS ordered the dinner and loved every bite.

I ordered Imperial Beef. It included, broccoli, carrots, mushrooms, cabbage, and water chestnuts. The vegetables were fresh and cooked perfectly. DD had Green Bean Chicken. I tasted one of her green beans and they were so good they inspire me to try cooking fresh green beans when we get home.

SS devoted most of the evening to studying. I asked him to explain something that he was learning that he had never known before. He said that he hadn’t known there are three systems to get energy to cells: Creative Phosphate, Glycolytic, and Aeorbic. CP provides a quick boost of energy and is rapidly depleted. Glycolytic can last longer than the CP, but glycogen breakdown is incomplete, so lactic acid is formed as a by product. Both of those systems are anaerobic.

The aerobic system uses oxygen and burns glucose. It can take up to 5 minutes to get this system functioning, but once it’s going it can continue as long as there are stored fats and carbohydrates available.

I’ve heard about aerobic exercise for years, and for the first time I understand why it is important. The first systems are only good for a sprint or for picking up a heavy object. They do not burn stored body fat. For weight loss, you don’t want a quick short burst of activity. Aerobic exercise is what allows you to sustain your activity and actually start to use up stored fat. This is why Dr. D recommends 30 – 35 minutes of exercise at least 3 times a week for Type As. For Type Os he recommends 45 – 60 minutes at least 3 times a week.

I find myself thinking of Green and his party again. As they paddled downstream, they were getting sustained aerobic exercise. But when they jumped overboard and swam for shore, they had to have switched to their Creative Phosphate and Glycolytic systems.
