In the UK we had petrol rationing because of the 1973 oil crisis & 3 day working because of the resulting power shortage. No street lighting, stores open but no power & factories having to close their doors.
We could almost 'taste' Armageddon in the air...........it all seemed to add up.
Blood transfusion was far more of an issue back then as well, no HLC's....... the JW's had to fight the fight on their own & as mentioned above some decided to put off surgery because the 'New World' would be here.
