Playing too much fps games has altered me. Nowadays I always have my right hand on my mouse and for the left hand i go with:
pinky: left shift
ring: A
middle: W
index: D or R
thumb: Spacebar.

altho when I start writing my right hand goes to:
pinky: Ä (right on the southeast of P)
ring: P
middle: O
Index: J
thumb: under spacebar.
