What are the peculiarities of bathing in salt water? This book I just read suggested that it was possible to do it in the morning, but not at night- is it the temperature of the water that makes the difference? What was going on?

I have been reading the questions posed here and I am beginning to worry for the future. If it turns out that most of the people asking questions are just attempting to be funny, I would be less concerned. So I must ask, are you people serious?

Where are they made? Who makes them? What kind of wood do they use. I saw a new kind the other day---made from plastic like stuff. Why not wood? Why plasticky stuff? Who invented pencils? Why? Where? When? How? How do they make some lead hard and some soft? Is it really lead or is it graphite? Where do they get graphite? What is graphite? I think it's really graphite because I've seen lead fishing sinkers and I've seen powdered graphite. It seems more like graphite to me. Besides, I have a pencil that says for its name GRAPHITE. That's what got me thinking about these questions.
When you look at a pencil and thiink about it, it must be pretty hard to get that stuff that writes down the middle track in the wood. Abe Lincoln did his Arithmetic on a wood shovel with charcoal. Is that really true? My guess: They drill a long hole through a tube of wood, pour in powdered graphite and powdered gluey stuff, then use heat and pressure, then let harden. BUT HOW?

Contrary to the belief of science fiction novel writers, we do not have flying cars, laser beams or ANY such things in "their predicted future". Why is it so?

I think it's pretty cool such an object can reflect exact images in color and shades. The same goes with water; you can see your own relfection when you look into a pond of water. How does this work? I know it has something to do with the way light is refracted against the surface, but how does light know what is in front of it? It's not like light can see in front of itself like people. If we're looking at a mirror and the light comes from behind us how is it we can still see our own image with no distortion if the light is behind us?

Within our mind, the regions in the frontal, parietal, & medial temporal lobes (i.e. the "dark network") the human mind can move through time from past to present or present or past to future and in any gear. Neuroscientists say it can be done! They know how to do this. Would you attempt this with help & guidance? They say you remember everything you see and hear. Scary isn't it?
