If you can change time and conditions, couldn't you do strikeout what you wrote before and replace it with *In t+50years, dies of heart attack.*

<p><a href="http://deathnote.wikia.com/wiki/Rules_of_the_Death_Note#How_to_Use:_XV" rel="nofollow noreferrer">Rule XV</a> states that</p>

<blockquote>
  <p>When the same name is written on more than two Death Notes, the note which was first filled in will take effect, regardless of the time of death.</p>
  
  <p>If writing the same name on more than two Death Notes is completed within 0.06 seconds, it is regarded as simultaneous; <strong>the Death Note will not take effect and the individual written will not die</strong>. </p>
</blockquote>

<p>So, if an individual is <em>very, very</em> fast he can save another from being killed by the Death Note (if you have two other Death Notes); this can happen as a <em>very</em> unlikely coincidence. But this rule states that "writing the same <strong>name</strong> (...) is completed within 0.06 seconds", so to save another life you need to write the name in the other two (or more) Death Notes soon after the name was written, and so <em>before</em> the causes of death.</p>

<p>So it's a task for <em>The Flash</em>... or maybe for <a href="http://cyborg009.wikia.com/wiki/Accelerator" rel="nofollow noreferrer">Cyborg 009</a> since this is the Anime &amp; Manga Stack Exchange.</p>

<p>Its not possible to stop the person dying from the written cause.
The Death Note has no provision for avoiding death until and unless the writer doesn't have the person's face in their mind when writing his/her name.</p>

Re your second paragraph: Yes there are. It's in that same rule. If the situation and cause are impossible, the Death Note defaults to a heart attack. Save heartless robots, a heart attack is never impossible.

@Jan I saw that the result of both the cause and the situation being impossible was a heart attack, but I didn't see anything in regards to if only the cause was impossible, such as if you wrote shot as the cause but they were surrounded by metal walls.

<p>Let's say I had a Death Note. If I wrote someone's name in the book and then wrote details of the death, can an individual stop the cause of death and the actual death entirely or will the death still take action, but in a different way?</p>

What do you mean by can an individual the stop the death? How would they do that?

This is, of course, as long as you thought of the victim’s face while writing the name. In case you now assume that you can just alter the details of death to something impossible, well sorry:

So, if an individual is *very, very* fast he can save another from being killed by the Death Note (if you have two other Death Notes); this can happen as a *very* unlikely coincidence. But this rule states that "writing the same **name** (...) is completed within 0.06 seconds", so to save another life you need to write the name in the other two (or more) Death Notes soon after the name was written, and so *before* the causes of death.

So it's a task for *The Flash*... or maybe for [Cyborg 009](http://cyborg009.wikia.com/wiki/Accelerator) since this is the Anime & Manga Stack Exchange.

So, hypothetically speaking, if an individual's name was written in the DeathNote and they were able to bring about events that would render the situation of their death impossible, they will still be susceptible to the cause of death.

*However*, there are no rules that specify what would happen to the victim of they were able to prevent the cause of death (be that if the cause was "shot through the heart" and the victim locked themself in solitary confinement for example).
