noise and coockies

Noise functions were somewhere years ago in Physics lessons at school. I was fond of physics. I liked curves and representation of sound as a curve and the possibility to show sound interposed one over the other. This is what noise is about. How come we cannot hear a sound when there is noise?
Can I hear something when I eat a coockie? Or many coockies? Or most coockies? When I drink? I rarely drink too much (less than once in 5 years), being a responsible parent. I'm affraid I drank too much coffee, and if I drink too much coffee I'm more likely to loose my sense of humor.

coffee, no regularity

Does coffee influence sequential thinking? I wondered after seeing pictures of spiders that made webs after drinking coffee. I was shocked to see how much effect coffee has on the pattern made by the spider.
I already quit drinking sugar in my coffee. Maybe I should quit coffee and drink herbal tea instead.
Maybe my coffee drinking behaviour is responsible for my "but first syndrom", rather than a chaotic nature?
