Should I rest my arms on my desk?

Should I rest my arms on my desk? It is acceptable to occasionally rest the arms at the elbows but be cautious of resting the forearms on the armrest for any prolonged period of keying and mouse work because this can compress the finger flexors or ulnar nerve. Armrests should be used for intermittent, light support with these tasks.
