Something worth noting, and I edited my OP as such...From the wiki link about polyphasic sleep - "...researchers such as
Piotr Woźniak warn that such forms of
sleep deprivation are not healthy.
[3] While many claim that polyphasic sleep was widely used by some
polymaths and prominent people such as
Leonardo da Vinci,
Napoleon, and
Nikola Tesla, there are few reliable sources supporting that view."
Obviously, as with anything, take what you get online with a grain of salt. Just sharing this all because it is intriguing, and I figured others here would find it to be as well!
Wait...Doesn't

fine?
