As humans, we're literally hard-wired to keep ourselves alive. As our understanding of health, wellbeing and ageing has improved, alongside advances in technology and scientific testing, human longevity has increased exponentially - and we're now living longer than ever before. According to research, we've hit an all-time high, life expectancy-wise, with the average UK adult living to 83 years (women) and 79 (men).
But there's a catch: our general health hasn't quite caught up, and we're now living in poor health for longer, with Government figures suggesting we're surviving in poor health for an average of 20 years - not an inconsiderable portion of our lives.
