I'm not sure that it has had an effect on my sleep, but, the not getting burned thing is holding pretty solid. I spent one day moving 1000+ pavers on a hot and sunny day and I didn't get burned at all. That seems to be an outlier at I'd normally expect to get burned on a day like that.

I just think it's good to start questioning what we assume are the foundations of our existence.
I've found the modern "foundations" to be flimsy at best and downright nefarious at worst.
