Interesting. And true, too… I taught myself to get to sleep very easily in my early twenties (I might write more about that if people are curious), but while running my previous business, there were a couple run-ins with malicious hackers that screwed up my sleep patterns immensely… I could still get to sleep, but I could only stay asleep for about six hours, which is usually not enough for me. It has been nearly a decade since those happened, and I still have to take afternoon naps most days.
