Can you kill a human with a Death Note in less than forty seconds?


If I were write in the Death Note:

> Bob Bold Heart attack NOW.

Would that work?




According to the first rule in [How To Use
III](http://deathnote.wikia.com/wiki/Rules_of_the_Death_Note)

> If the time of death is written within 40 seconds after writing the cause of
> death as a heart attack, the time of death can be manipulated, and the
> **time can go into effect within 40 seconds after writing the name**.

So the time of death (e.g. "NOW") won't go into effect for 40 seconds.
