Thank you! :)

I recently did some night sift work and I got to say seeing people who do that kind of job regularly, you can tell the difference in their faces, energy levels and also heard that if the sleeping patterns move around a lot, some people have issues with digestion.

Night time for me is a very creative time. Always been that way. Not a morning person at all. Usually feel low on energy entire day if I had to wake up earlier than I naturally would. So I think you are right about that :)
