While out walking today, my son asked me another question I couldn't answer. He said that we're all told not to look directly at the sun, it's bad for our eyes; but what if a camera had filmed the sun, then we watched it on television - would that still be bad for our eyes?
I can only raise my left eyebrow by itself to look quizzical. My
right eyebrow won't work in the same way, although I can do both at
once. Any ideas why this is? I'm right-handed, if that helps.
