OTOH, doing it for a living for nearly 65 years, there were years at a time when they came on with the bench lights at 8AM, & didn't go off till the bench lights went off at 17:01 as we were walking out. That adds up to 45 hours a week, more if you're late and putting out fires. That original black one did that for probably 15 years. Even at a 'retired' 77 now, I am probably averaging over an hour a week. I 'keep a hand in'. ;-) Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
