Facts to know about your Coffee
"How does it keep you up?" -
The shape of caffeine is similar to an important molecule called “adenosine” that regulates brain function. Caffeine “mimics” adenosine and binds to the same targets in the brain. 
During the day, your brain naturally builds up its levels of adenosine. When they reach a threshold concentration, they bind to special receptors that react by start firing instructions to make your body sleepy.
Remember how caffeine has a similar shape to adenosine? This means that it can bind these very same receptors, blocking the natural effect of adenosine. This allows the brain’s stimulants to work unimpeded, keeping you up and alert.

"when will the acid kick in?" - 
After as little as 10 minutes, the caffeine concentration in your blood reaches half the maximum concentration, which is enough to have an effect. The caffeine reaches maximum levels, making you most alert, after 45 minutes. Depending on how fast or slow your body’s able to break down the drug, you could feel the effects of caffeine for 3 to 5 hours.
coffee may be good for health - 
caffeine, and many other stuff in coffee has been proven to reduce the risk of death by natural causes

That’s because coffee also contains hundreds of different compounds. These include many antioxidants that protect our bodies from oxidation by damaging chemicals called “free radicals.” These molecules cause aging and are associated with illnesses such as cancer and heart disease. NIH studies show that coffee drinkers have a reduced risk of Alzheimer’s, Parkinson’s, type 2 diabetes and many other diseases.
Don’t drink too much - 
your brain can become unhealthily addicted to caffeine. As you might expect, the brain is clever and not so easily tricked. In reaction to caffeine blocking all of its receptors, the brain makes even more of them so that adenosine is still able to bind its target. This means that over time, the chemistry of your brain changes so that you’ll need to drink more and more coffee just to have the same effect.

Caffeine is a stimulant to the central nervous system, and like other drugs, regular use of caffeine can cause a mild physical dependence. Caffeine withdrawal is now recognized as a mental disorder. So consume carefully.
spiders cannot cope - 

In 1995 NASA tested the effect of various drugs on the ability of spiders to spin webs. As you can see the result is quite striking. Spiders can’t metabolise caffeine as well as humans, so they are much more affected by the drug.
Seriously, don’t overdo it - 
the lethal dose for coffee in adults is 100 cups in four hours…. try maybe two or three a day.
