A Canadian friend's father was a RAF Spitfire pilot during the battle of Britain. He was very meticulous about cleaning, replenishing and caring for anything borrowed. I commented on this. He told how in WW2 he took up a ship usually flown by another squadron member. He found himself on the business end of a BF-109E and returned to the field in a lorrie and an unpacked parachute. His mate was apopletic about "his" spit being destroyed. We have a throwaway society. My Grandfather's 60 y/o straight razor was never touched by anyone. Today I find my disposables walking down the hall in my cat's mouth or my nephew's spit kit. For a materialistic society, we have a poor regard for material :O(
