If you have a long shadow, the sunlight that gets to you has gone through much more atmosphere which attenuates the ultraviolet light. So at high/low lattitudes and during morning/evening hours the amount of uv that gets to the surface is much lower.
Still I don’t understand does shadows have something to do with vitamin D ?
No. It means how high is the sun.
With booze and mushrooms and so.
And maybe a little weed, I heard sun Doesn’t even need a lighter to light it so must be a pro at that .
6/9 Blaze it
