Wonders of my world

Out of boredom and lack of sleepiness, ever wonder what happens inside a cremation chamber? Well, the truth of the matter is: no one alive would ever know. Even the ones who own the crematorium would never ever really know how it looks like in there while it's happening. Ever wonder why Geisha's take bids for the first ever sex they'll experience in life? Was it customary that they did or was the money they would get from it gets donated to some charity (If it existed before). Ever wonder where feelings really come from? Is there a specific organ that generates them? The hypothalamus? The heart? The brain? Ever wonder how other government agencies capture clear photographs of people they we're spying on even if  they we're nowhere to be seen while it was taken? A satellite that's miles away? A super camera that was never released and announced in public?  Ever wonder how scary it would have been if we experienced Dinosaurs? Could we have survived? Ever wonder why dragons are so fascinating? Could it be because they're fictional characters of a genius who thought about they're so called existence before? Ever wonder why Google is so amazing? Maybe because we can type anything we want on the search engine and get results right away. Effin' genius! Ever wonder why some are awfully rich and cannot think of a way to spend their millions anymore while others are slaves for them? Maybe because they we're born rich but cursed? Maybe because they worked hard for what they have? Maybe because some are not ambitious enough for them to have what the rich has? Ever wonder why some people are addicted to something? What causes it? How the hell did the addiction start anyway? Who and what triggered it? Ever wonder why constellations are formed? Why were they formed? What are their purposes? Ever wonder how stale wine is made? I know how but I wondered about that before. Ever wonder if dogs can smile or make face? Do they frown if you tell them to go to the tub for their bath? Do they smile like a 4 year old when you're about to go out for a walk with them and when you're about to give them a treat? Ever wonder what your pain tolerance is? What measures it? A weighing scale? A thermometer? Or a specific tool that's unknown to me until now? Am I the only person who doesn't know about this? Ever wonder why every person in the universe can be distinguished by fingerprints? Whose idea was this? Why do we have different fingerprints? Are there people who have the same, identical ones? Ever wonder why we wonder? Why are we curious? Who can answer our questions? Am I crazy? What caused my curiosity? Am I overcurious? Is this something normal? Is it healthy to be curious?
