Does DNA have a finite life time? What causes it to deteriorate?

DNA is degraded in cells via DNAses which break the bonds in the DNA. DNAses require Mg (magnesium) as a co-factor in order to work so if there is no Mg available the DNAses cannot breakdown the DNA. Products like InstaGene are used to preserve DNA in this manner so the DNA can be used later.
Other conditions, such as water availability, bleach and other chemicals, and desecation level will also damage DNA. Assuming none of these factors are present DNA could last a very long time (>1000 yrs), but it is very unlikely that this would occur.

it does last a while, even when a person dies for hundreds of years-since they do analysis on people they find hundreds of years later (history channel :) ). It can be damaged but doesn't it repair itself?

dna is replicated everytime a cell in your body duplicates. so im guessing that it lasts as long as your decomposing body does.
