What is this shadow longer than your tall thing ? I have never heard of it lol . Can you explain how to check it or why it is a thing that happens and is real ?
I think that’s saying that if you go out at sunrise/sunset, the sun is on the horizon, and so your shadow will be a lot longer. In that scenario, you aren’t getting enough UV to produce the vitamin D you need.

Still I don’t understand does shadows have something to do with vitamin D ?
No. It means how high is the sun.
