Yes but why?

Why do we feel better after taking one leg out of the blanket? Why glue does not stick to the internal part of the tube that it comes in? Why do we love dancing in the rain but can't stand it when a single sock is wet? Why do they use sterile injections when executing someone who is condemned to death? Why do we have to sleep to function properly? Why do we feel hungry when we're bored? Why do we press down harder on the remote controls despite knowing that the batteries are low? Why is it that when someone hits us in the ankle with their trolley in supermarket and apologises we say its ok, Why is it that we do not say that it hurts? Why our hair looks better just when we're about to take a shower? No matter the color of the soap, the bubbles are always white, why? Why did the Japanese Kamikaze pilots wear helmets during the Second World War? Why does Superman stop bullets with his chest but, then, duck when the vacant weapon is tossed at him? Why our dreams are always so stupid? Why do banks charge a commission when you go into debt even though they know that there is no money in that account? Why do people go back again and again to the refrigerator hoping that something new to eat will appear? Why do we eat some of the fruits along with their seeds and some seeds we take out? Same with the vegetables. Why do people believe it when they are told that there are more than four billion stars, but when they see a sign that says wet paint, they have to touch and check? Why does a plastic sack not open toward the end where you first attempt to open it? Why do you never hear jokes about fathers-in-law? Why are there dead bugs inside encased electric lights? Why is it that every time you try and catch something about to fall off the table, you always hit something else and drop that instead? 

Life has many oddities and conundrums: some funny, some less. And I am sure that there is a perfectly logical explanation for some of the questions I've written but some just don't make sense.
