1) They are completely anecdotal. "This worked for me, so it applies equally to all 7+ billion humans on this earth!"
2) They assume that everyone lives in the same climate and/or lives in a similar region. e.g. How are you supposed to 'connect with nature and the sun' when you live in Alaska and it's dark 6 months out of the year? How are you supposed to regularly 'connect with nature' when you live in the middle of a metropolis?
Seriously. Forget alaska, I live in the northeast and this time of year it is dark before I go to work and dark when I get out. And it is mostly gray inbetween. Right now it is borderline freezing and pouring rain out there, I choose the gym over my usual jog this morning. There was no Vitamin D to be had anyway.
