Perhaps one could not live with such knowledge. One might die for it, or of it.
Ignorance has its own advantages.
வாழ்வின் பல தருணங்களில் அறியாமைதான் சந்தோஷம்; அறிவு நிம்மதிக்குச சத்துரு.
...sometimes it's best not to know, because even when you know, it doesn't matter anyway. Ignorance is bliss. Knowledge is often a responsibility nobody wants.
