Too true. I was cruising in a 737 Classic at 31,000 ft somewhere Germany and Greece. It was a beautiful day and I decided to practice tracking the VOR on flight plan route instead of VNAV and LNAV. Told the young 250 hour German first officer that was I disconnecting the autothrottle, autopilot and flight director and keep my hand in tracking the VOR's.
He looked at me completely disbelievingly and announced "In that case I will don my shoulder harness." Words failed me.
