It seems to me, that if there was a large amount of "junk DNA" in our chromosomes, it would be advantageous for much of it to be at the ends, preceding those telomeres. That way, when you start to run low on telomeres, you would still have quite some time before you start losing "important" DNA and suffer that horrible death. It's also possible that I am misunderstanding how telomeres work.
