Why don't we say: burning the 'midnight electricity'?In earlier days there was no electricity. So, the people who used to work at late night or the students who studied at night were stated to be 'burning the midnight oil'.
However, now electricity has reached every nook and corner of India. People/Students of remotest areas of the country nowadays study in electric light. So, I think the old usage/idiom 'burning the midnight oil' is now urgently required to be changed/modified. Can't we now say: 'burning the midnight electricity' instead of the old idiom?
I feel that this change is necessary to make the language evolve with time. Members may kindly give their opinion on this issue.
