ive just always wondered these questions..and i searched you and you seemed pretty smart <3
#1 If you get chemo-therapy do you lose your pubic hairs,arm hairs,leg hairs, or facial hair?
#2 Where do all the daylight savings hours go?
#3 If mirrors need light to work, what happens if you put night vision goggles on in the dark and look at a mirror?
#4 Does a baby feel the umbilical cord being cut off?
#5 Why can't liquor freeze?

Well, I'm no Marilyn Vos Savant (I.Q. of over 200), but I'll give your questions a try.
#1 - There are several types and regimes of chemotherapy. Some of them are weak enough they don't even cause significant hair loss. Others, especially combinations of several strong drugs, make you lose EVERY hair, including the hairs in your nose and ears, your eyebrows, eyelashes, pubes, toe hairs, everything. Some of them are strong enough to cause the hair cells inside your inner ears to die, causing deafness. Chemotherapy prevents rapidly-dividing tissues, like our hair and the lining of our guts, from growing. That's also why it makes us puke a lot and why it kills babies in the uterus.
#2 - The hours in daylight savings? Well, what we call time is just the subjective measurement of the objective reality of time. We can measure it in hours, but just because we say it's 2:00 doesn't make it so. It's just our shorthand. In the spring, we skip an hour so at 2:00, we say it's 3:00. Then in the fall, we repeat 2:00 to get back on schedule. We could accomplish the same thing by saying that we're all going to work from 7-4 instead of 8-5 from April to October. We can't make time either appear or disappear. The same applies for Leap Day, when we add an extra day to our calendar to adjust for the fact that a year is not truly exactly 365 days long. It's off by a few hours, which we save up and take once every 4 years (with exceptions). We change our clocks with Daylight Savings Time so that we are awake and doing business during more of the time when the sun is up. That is supposed to prevent accidents and save money and energy on lighting.
#3 - I asked Xenolan about this one. He says night vision goggles work on a different wavelength of light. They give off this light which we can't see unaided. If you looked in the mirror with nightgoggles, you would likely see the glare of the special light being reflected back at you. It might shine a little on your face, but you may not be able to see your face in the mirror.
#4 - A baby doesn't feel the umbilical cord being cut. The umbilical cord has two veins and an artery, but no nerves. It is part of the placenta's tissue, not the baby's tissue. Like hair, it is human tissue, but lacks pain sensors. Now, the umbilical cord attaches to the baby's belly button (umbilicus), but once the blood supply from the placenta to the umbilical cord is cut, the cord dies, turns black, dries up, and falls off after approximately 10-14 days. Sometimes there's a little bleeding where the cord was attached to the baby's belly. I don't think it hurts, but maybe it's like pulling a scab. I've only seen a couple of them fall off and the babies didn't seem to notice at all. Of course, they're only a couple of weeks old at that time and they don't tend to say "Yo. There's something funky going on right there."
#5 - Why can't liquor freeze? Well, it can. It depends on the content of ethyl alcohol. The higher the alcohol content, the lower the freezing point is. It just has a lower freezing point than water does. It's molecules are not as close together as the molecules in water. Pure ethyl alcohol will freeze at approximately -114 degrees C. Household freezers are about -10 degrees C.
Thank you for your confidence. I hope I helped!
