Now here is the thing: studies have shown that sleeping less than 5 hours WILL have negative effects on your body and mind and on your ability to do any job... and frequently or constantly sleeping less than 5 hours even more so, it can even cause hallucinations. And severe lack of sleep can be directly compared to the negative effects of alcohol on your ability to do any work.
But we are applauding the one and frowning upon the other...?
How ridiculous is that, really? Someone with as many responsibilities as a CEO for SAP India openly admitting to only sleeping 4 or 5 hours daily should be treated like someone who just openly confessed downing a glass of vodka for breakfast and lunch each day. And I strongly doubt his "ability" to pull that off... I would imagine someone so competitive and successful and career-focused with that little sleep would not refrain from relying on a little chemical "help". And even if he was still productive enough, just imagine how much better he could have performed if he actually got 6 to 9 hours each night?
This is really nothing but grossly negligent IMHO.
