[Death Note] Is there a time limit for deaths? Can I write as a cause of death that "so-and-so dies peacefully in his sleep at the age of 93"?

No, you cannot do that (unless the victim is already 93 or very close to it).  The maximum amount of time you can specify is 23 days (assuming that the victim’s lifespan is longer than that, of course).  Attempting to go longer than that or exceed the victim’s remaining lifespan will just cause the victim to die of a heart attack 6 minutes and 40 seconds after writing their name down.  And if they only have 12 minutes or less left on the clock, the Death Note simply won’t work at all on them.
