According to the old saying, age is just a number, although exactly what that number is and how much time we have left is open to interpretation. Many of us might be satisfied to see three score and ten, while others hold onto their youth like the proverbial Peter Pan. Some among the so-called billionaire elite even imagine they can cheat old age through cryonics, freezing their bodies after death in the hope that technology might one day be advanced enough to revive them.

Whatever method we choose to keep age at bay, none of us are immune from the inexorable march of time and while UK government figures show that life expectancy is increasing (27% of the UK’s population is expected to be over 65 by 2072), longer lives come with their own issues (‘Preparing for an ageing society inquiry launched’ – committees.parliament.uk).
