Thanks! On the other hand, I ended up catching a nasty cold...win some, lose some. I looked on the googles and I didn't get much clear information about how to increase deep sleep since going back in time to be 20 years old doesn't appear to be an option right now. I like having the information too and it's amazing to me how often I apparently wake up at night for a minute without realizing it. It will be more interesting to me after I've accumulated a few months' worth of data but even right now it's fascinating to me. I'm about 90% over this cold. I ran for the first time since I got it and it wasn't awful, but I didn't feel strong either. Mentally, that's the most difficult thing for me, feeling as if I lost ground. The cold kept me home from work for three days which I think pretty much ties my all-time record for most consecutive workdays missed. The last time I missed 3 days of work was probably 2013 due to a pretty serious back injury. But it was the smart thing to do and I feel almost fully recovered. Tonight we go to see friends at their house for dinner and tomorrow is a day when I can get a lot done around the house and hopefully have a stronger run. Nutrition this week has been so-so but I've still resisted eating sugar or gobs of junk food, which is making me feel good about myself.
