A CUP OF COFFEE AND A GLASS OF WATER

Actually i really love Tuesday, Saturday and Sunday now...
because these three day, I will have enough time to drink and enjoy my coffee...
usually, if I have enough time, I always drink a coffee accompany with a glass of water...
do you know why??

According to principle of economy, when you drink a cup of coffee
your marginal utility will decrease continuously...
mean that when your utility will become lower and lower per drink....
why this happen?? how come??
the reason is your mouth...
before you drink your coffee... your month haven't any drop of coffee...
so at the beginning, coffee concentration in your month is zero...
but after you drink half of cup of coffee...
concentration won't become zero although those coffee already flow into your digestive system.
so when I drink coffee, I will drink some water to clear coffee which still remain in my mouth...

so the conclusion is, drinking coffee also a knowledge...
Haha...actually this post is rubbish...
