I'm Indonesian weighed 54kg and 168cm tall.
My daily activity is working in my desk. When I heard that 1.5 liters water is myth, my concern is what about people in tropical country?
If I just measure requirement by pee color say if it has clear looks I'll try reduce water until it's still looking clear. This way I came up with about a liter per day (peed 6-7 times). Personally I disagree with thirst indication as it always too late.
Is there a difference among tropic kidney and cold country kidney?
EDIT: I eat raw fruits (guava, banana, orange, etc) daily and not a coffee drinker
