Several pages back, there were questions about cloning and accelerated aging.
Technically, clones should be subject to it unless certain issues are overcome. Normally, our bodies produce telomerase until about 30 years of age. In cases of progeria, it would seem that those children have never produced it and due to the rapid cell-divisions that are normal during childhood, appear MUCH older than they actually are.
Now, with cloning, clone would essentially inherit the "state" (or age) of the telomeres and telomerase of the subject being cloned. If that subject were near enough to their thirties (or already above) then accelerated aging would be likely to set in.
Interestingly, treatments for telomere/telomerase related premature aging have shown that you actually CAN de-age people buuut it seems to result in one of the main things that they normally protect against (cancer). Kind of a lose-lose situation but if you could overcome the issue of cancer, you could be physically in your mid-late twenties basically forever.
Also, I've ALWAYS felt that MGS was largely influenced by a book written by David Rorvik titled "In His Image: the cloning of a man". Rorvik maintains that the cloning described in this book did in fact take place but has never provided evidence.
That said, some of the hurdles described in that book were indeed found back when the sheep Dolly was cloned.
