Some politicians are making big claims about longevity to justify their health and social policies. Are our politicians on the far right simply fantasizing about living longer? Is this why they tell us good health investment should be directed towards curative research alone while everything else to do with health is lying under a precariously balanced metaphorical bread knife. How would you like that sliced – thin or sandwich? From a cynic’s point of view this claim might simply be about appealing to the core of individualism and what’s in it for me? An old tactic repackaged.
Sure many scientists are making claims about future generations reaching incredible ages but I am sure they will agree at this point in time these are theories not proven fact, possible, even likely, but still theoretical. Certainly our average life expectancy has risen as health care and living conditions have improved. Hans Rosling is very entertaining on this issue.
It is a fact that better access to health services and better living and working conditions improve the overall health of a population. One day some people might live to 150 but these results depend on future discoveries and advancements in biological interventions such as gene therapy. Such projections are speculative and assume scientific progress will continue uninterrupted and treatments will be equally affordable and available to everyone. Living longer, if indeed we do, might be the privilege of some people and not others depending on the social policies we choose to adopt.
My argument goes like this. In my opinion, human beings have always been a pretty arrogant lot. We really do believe we are superior – to other animals, climate etc etc. We particularly hang on to the belief that we can tame nature and we do – to a point. How many examples of nature doing what it does do we need to show us that although we might be on top for a while it won’t necessarily last – at least not without some counter reaction. A prime example is antibiotic use and the development of antibiotic resistance. When we triumph over one disease, a new one seems to emerge to take its place – smallpox, AIDS, Ebola, take your pick. According to one recent study, although average life expectancy is higher, this generation has a different set of health issues – more metabolic disease. The effect of this shift in disease on our future life expectancy is unknown but can be hypothesised. We already know the long term impact of these diseases on our health but on the other hand we don’t know the influence of future medical treatments yet to be discovered and made available.
There are other factors to consider when contemplating our longevity. We have known for some time health is more than biological and that social factors and social policies impact on our health. We only need to look at work on inequality and studies on the health of particular, improverished populations such as the people who live in the Gorbals, south of the river Clyde in Glasgow.
Alarmingly social policies and where governments choose to invest does influence longevity and health. We only need to look at health outcomes for Indigenous peoples in places like Australia and Canada and recent findings that life expectancy has reduced in some areas of the UK. This backward shift is being linked to the reduction of services that maintain health and well-being. Even if some people manage to live to 150 it may not happen for everyone equally. Assuming good genes and discoveries in curative and genetic medicine, all people will still need access to good healthcare. The seeming dominance of far right ideologies that promote policies of user pays, a sole focus on individual responsibilities, privatisation and purely biological approaches to health combined with a failure to address inequalities will continue to negatively impact on the health of many people. It will mean only those who can afford access to services will reap health benefits.
Sure average life expectancy has improved but has the end point actually changed? We have always had centenarians and a very few sparky souls that live to extraordinary ages, a rare few reported to be a 120 or slightly more.
This is not new and I doubt if modern medicine has had too much to do with it. Perhaps someone can answer this for me – have we actually extended our lives beyond the upper limit of our bodies’ use-by date? To put this simply, has the oldest age anybody has ever actually lived changed? Difficult question as many lives are unverifiable. I don’t think so – it may come but it will depend on more than biology and must include the social. Perhaps also there is a certain truth in that when we cure one thing, something else emerges – whether this is disease, climate change or even the stuff people are pumping into their bodies to at least appear younger. For the moment, future generations living to a 150 remains predictive and speculative. We all need a better approach to health than one based on profit or policies that make it harder for people to access healthcare or improve their lives. And so if it does come true and we manage one-day to live past our current use-by date, I hope it comes true for everyone not just a few.
