I want warm water, not a complex algebraic equation.

So, I was watching some old silent movie starring Hitler when suddenly it came to a bathroom scene.  I noticed Hitler had to use two levers to control the temperature of his faucet water.  I put down my bong and thought to myself...  "Hey, I have to use two levers too!"

Then I thought, "Why the fuck do I have to use two levers?"

It's 2011, haven't we developed the "warm" water lever yet?  Why do I need an engineering degree to calculate the temperature of my water?  Some strange system of degrees, pressure and toilet-flush/time ration bombard my day every time I want to so much as splash some water on my balls.


Then you also have faucets that don't want to give warm water, instead you're granted a second of scalding water and a second of sub-zero water.  Quite frankly it hurts my head and makes me want to do this:

Only I kill myself in the process.

I can take a shit and take a picture at the same time on my webcam, why can't I get warm water the moment I need it?  How come plumbers are so far behind on the times?
