Hot on the left is not right for right handed frugalists..

[Kaleva]

3. Which hand is dominant depends on the task.

I'm left handed for writing, eating, and washing dishes. With my right hand, I hold a cup and wash myself, smoke, throw, shoot and use power tools, scissor, snips and chop wood. For many hand tools, I'll use either hand. I'm more comfortable using a rake on my right side and raking to my left but prefer shoveling dirt to my right.

As for turning on the water at a two handle faucet, either hand works for me.
