If you're among the lucky few, you'll live past 90 without suffering years of debilitating illnesses. Your final decline will come swiftly and relatively gently. In this week's Discovery Andrew Luck-Baker looks at whether scientists can extend this kind of final exit to many more of us. Their research centres on structures in our cells known as telomeres. More immediately, this science may also lead to a kind of new cancer therapy.
