If you want to talk about dangerous, let's talk about that big ball of glowing hydrogen in the sky. If you let the light from that ball hit you for too long you can be badly burned, up to second degree burns. If you limit the time you allow it to hit you, but let it hit you nearly every day until you are 30, you can develop severe skin cancer. And, if you look directly at it, you can be blinded. Maybe we should look for a less bright ball of hydrogen?
