Staying up late at night will destroy you.
The study suggests that late time patterns (i.e., going to bed and waking up late) are associated with an increased risk of type II diabetes, even after taking into account other factors such as lifestyle and dietary habits. The results showed that people who prefer to stay up late have a 46% higher risk of diabetes compared to those with an average time pattern. This association is thought to be related to circadian rhythm disturbances, which can affect metabolism negatively.
It is amusing you're quoting "studies", and offer your golden farts of wisdom not taking into account context or actually relevant studies which would enlighten you as to why such and such happens in specific case... Your stupidity, naivete, obnoxiousness, primitivism, and arrogance, is a very dangerous mixture.. Stop talking about things / issues which you know nothing about.
