arghh... when I was at Primary School ( in England )we had a weekly Mental arithmetic test and a weekly spelling test - used to hate it.
Actually aircraft air-con had left and right sections, not back and front, but the obvious choice, smokers to the left/right (!) was never implemented. It's still not illegal to smoke, it's just against conditions of carriage i.e cheaper for the airline saves on cleaning and they circulate fresh air less so saves on fuel.
But as incrediBILL says, we have been lucky ! seen the first digital watch and calculator, the first computers, men on the moon, the original Star Trek series (!), England win the world cup, the Olympics in London, the fall of the Berlin Wall etc etc.
not so lucky to have seen [oh thats political so the mods will be lurking and I'll get the dreaded <snip>]
