It is ( or should be ) well known that the brain uses sleep to sort organize and digest information. In addition it is known that we require sleep for the physical conponents of our bodies.. Muscles etc. There are studies in controled environments that show: the more rested a person is, the better that person operates.

It always amazes me how most people seem to "give props" to those people that brag of staying awake for a long time. When we should be offering our words of complement to those that rest when it is needed.

OP: I agree. Yoshida should sleep more. But NOT as a thank you for 22hr shifts. As an intelligent human being he should sleep because he knows its a better way to function in his job.
