Day of rest. Went to church. We had another departing missionary speak. This is quite a difference from our old ward where we might see this maybe once every two years or so. The Sunday School lesson was on the last words of Nephi, so 2 Nephi 31-33. At the start of the lesson I was actively participating and making comments. However, towards the end my body decided to remind me that I had a sleep deficit after running 96 miles with increased intensity last week. So I drifted away and continued to learn via Lehi's dream. This gave me the needed boost for the Elder's Quorum where the lesson was on Elder Bednar's talk on family history. I was able to stay awake, pay attention, and actively participate in the lesson.
Took a long nap when I got home. Vigorous exercise is a very effective treatment against insomnia. I would highly recommend it.
