And finally, is it all in our DNA?

Although there are measures we can take to help us live a long and healthy life, there may be an element of luck involved – depending on our DNA.

Much research into ageing has been focused on the role of telomeres. These are the protective tips found at the end of chromosomes, sometimes likened to the tips of shoelaces. Their role is to safeguard the end of the chromosome and to prevent the loss of genetic information during cell division.

Each time our cells divide, the tips of our telomeres become shorter. Eventually they become so short, they stop our cells dividing which means the cells die, which is how we age.

Studies have revealed that longer telomeres have been linked to a longer lifespan, while shorter telomeres have been linked diseases such as heart disease and dementia. Longer telomeres can also be inherited by the next generation.

Maybe one day in the future, we will be able to predict how long we will live for.
