Now that summer is approaching, I urge anyone who still believes that the sun causes skin cancer and that sunscreen protects against skin cancer to read these two posts that I am sharing here, thoroughly.
If you still have the same belief after you have read this, then you obviously have no ability of logical thinking or you just don't want to admit that you were wrong (also called as cognitive dissonance).
This is so obvious so anybody (who wants to) should be able to see and understand this. It isn't rocket science.
