Can we live for ever?
Answers
Answer:
We live in an amazing time: we’re starting to think of “ageing” not as a fact of life, but a disease that can be treated and possibly prevented, or at least put off for a very long time. Our knowledge of what causes us to age – and what allows some animals to live longer than others – is expanding rapidly. And though we haven’t quite worked out all the details, the clues we are gathering about DNA damage, the balance of ageing, metabolism and reproductive fitness, plus the genes that regulate this, are filling out a bigger picture, potentially leading to drug treatments. But the real question is not how we’re going to live longer but how we are going to live well longer. And since many diseases, such as diabetes and cancer, are diseases of ageing, treating ageing itself could be the key.
