Still researching sleep here. Holy cow, I found out that human growth hormone promotes deep sleep and vice versa. Positive feedback. The best I have slept in the past 10 years was when I was deadlifting once a week, my husband says, and he remembers better than I do. I had to quit over a year ago because of an injury. But I did some weightlifting today, and I'll be doing more, building up. This should help. I got into swimming this year and the little bit of lifting has just tapered off to nothing. I feel hopeful.
