What are you thinking people in India dont know anything?
Simple stuff like drinking alcohol, they know to eat it with some fried protein.
Mostly if you see, the guys who visit alcohol shops by the road side drink and eat some fried eggs or fish.
Why?
Cos presence of oil and protein retards the sudden rise of alcohol in the body..so the kickku is a slow and steady rise and this allows a person to consume more.
How did they know all these?
Well, I studied it from medical books but the guy who is having a quarter cutting, he inherited this knowledge from the keen power of observation of his elders.
Dont worry about India, they know their stuff well.
