Age shall not wither us Kate Jones Age cannot wither her, nor custom stale her infinite variety. Anthony and Cleopatra Act 2, scene 2 Some neuroscientists believe that we are at a new frontier in the evolution of human consciousness. Harvard developmental psychologist, Robert Keegan, believes that, in addition to the four stages of development that have already been established, our increased longevity means that there is now the possibility of a fifth stage. But what is even more interesting is his hypothesis that what we are witnessing is a further stage in the evolution of humanity. He posits the idea that we are living longer for a reason - to preserve the species. The fifth stage of development involves, amongst other things, the capacity to increase our ability to think in more complex ways: less 'either/or' thinking and more 'both/and' ways of looking at the world. This leads to not just increased empathy but an increase in our problem solving skills. The poet John Keats appears to have been even more precocious than we thought since he was only in his twenties when he wrote about the concept of 'negative capability', the possibility of holding opposing concepts in the mind simultaneously, an idea that fits with Keegan's description of the fifth stage. I think Keegan's idea adds a whole new, and extremely exciting, spin on the subject of ageing; one that goes beyond anxiety about pensions and health care and offers an empowering sense of optimism for those of us hoping to progress to this fifth stage. First of all, let's examine those current anxieties about increased longevity. At a TED X Women conference in 2011, Stanford psychologist, Laura Carstensen, told her audience that, “More years were added to average life expectancy in the Diet & Health Today C20th than all years added across all prior millennia of human evolution combined.” That is a staggering statistic and it has been assumed that an ageing population will mean huge costs to health care systems and social security. But does it have to be that way? There are challenges ahead, it would be simple-minded not to acknowledge that, but there are also opportunities to make some dramatic changes in our attitudes to ageing and to the very organisation of our Western societies, and maybe even beyond that to the fast developing countries elsewhere in the world. We are all more than familiar with the argument that people who are now over fifty will have to work for longer and delay retirement; otherwise we face the prospect of the younger generation having to work harder and pay more taxes in order to be able to support us. But, given this vastly increased longevity, surely it’s a no brainer that we should continue working for much longer if our average lifespan is likely to be nearer to ninety than sixty to seventy, as it was in 1940 when pensionable retirement age was set at sixty for women and sixty five for men? Why is this prospect of a longer working life so often perceived as a negative? Is it because we are worried about the cognitive decline in older workers? Should we be? Up to date research in neuroscience and psychology suggests we need a rethink on this too. While it’s true that you might find yourself unable to remember the name of a colleague you were introduced to yesterday, the good news is that you will be able to think of ways round this embarrassing predicament more easily than your younger self. A study in the Journal of Gerontology 2007 found that older adults get better at solving interpersonal dilemmas. In the above case you could try, “You know, I didn’t catch your second name yesterday” - sometimes the second name will trigger the first name; or you could just smile charmingly and 'fess up that you’re hopeless with names, always have been…" ; or “I was too busy concentrating on the 9
