This information about receptor sites in the eyes makes me wander about circadian rythms in the blind. I have been noticing through living mostly completely in the nature these past weeks with nothing but my hammock that I am going to bed a waking up much earlier. The sun sets here at 6 and by 7 I finish up eating and by 8 I am ready for bed. We are meant to live with the sun as all of nature has evolved with it's cycles. The indigenous tribe we were living this showed the health of connecting with the sun quite well. At 5 am as the first rays started to crack over the horizon I could hear them starting with wood chopping and from there had a very productive day. I feel that they looked down on us when we would sleep untill 7am as though we were waking up late.

Also thankyou because I just saw you resteemed my last article. It means alot to have the recognition of someone with such thoughtful and well written work. I enjoyed this article and learned alot as always from you.
