1. Wash your hands before your meals?
Almost everyone uses spoons, forks and knives. That small tip might need to be removed from our coursebooks. And even if we used our hands, the food, themselves have so much filth in them these days, that they would need more cleaning and disinfecting than our hands.
2. Honesty is the best policy?
Haha. That one surely needs some immediate attention. Well, maybe, not such a drastic change. "Find and replace" all occurrences of "Honesty" with "Dis-Honesty".
3. Justice is same for all?
Really!! Ahem... Do you even need examples?
4. Look left, then right, and then left again before crossing the road.
In today's world, you can't follow that. Vehicles have taken to the footpaths. You should pray to God before stepping out of your houses.
5. Sources of water?
No. Not wells, freshwater lakes, ponds or rivers. You get water from the tankers that visit your building premises every morning.
6. Constitution. It clearly specifies the limits on the powers of a Government.
I almost had forgotten that one. But, that too, needs to be amended now. Umm. Maybe, it's not needed anyway. The Government is all-powerful, and it can and will override the constitution as and when it feels it needs to.
Thank God, that the laws of physics haven't changed. And the maths that we learnt still works.
