It might be interesting, just a suggestion to write down for each day when you went outside to get sunlight and when you did that, relative to waking. So you would write down, like the way I do this in my calendar is I'll write down that I don't get exact about it. I might say, I woke up at 6:15 and then I, as I'll put a W 6:15, and then SL for sunlight and you'll sometimes get outside right away. Other times I'm less good at that. I'll go out around, let's say seven and for how long, I don't maybe like 10, 15 minutes or so. And then I'll put a little check at the times that I eat my so-called meals. Although, as I mentioned, sometimes my meals are a bunch of small checks that just kind of extend through the late hours of the day. Yours might be more confined to certain times. And then you might just take note of when you exercised, just put down an E for when you exercise. Weight training or aerobic exercise. And you might note when you might've felt chilled or cold if you do, or you might've felt particularly hot, or if you woke up in the middle of night, when you felt particularly hot. And then the last thing you might want to do is just write down if and when you did a non sleep deep rest protocol,
