After many years of research, Dr Elizabeth Blackburn (along with her colleagues – who won the 2009 Nobel Prize for medicine for their discovery) – concluded that we can directly link ageing to our chromosomes.
Dr Blackburn explains that all the cells in our bodies carry chromosomes that are capped at either end by telomeres, which help to protect the chromosomes. But these telomeres wear down over time and eventually fall off – resulting in signs of ageing.
But there is hope. According to Dr Blackburn, we do have some control over how short our telomeres get – and while we can’t extend our lifespans, we can make changes to live healthier for longer.
So what can we do?
Manage stress: more stress equals shorter telomeres so it’s important to find ways to cope with stress successfully. “Attitude matters,” Dr Blackburn says. “If you typically see something stressful as a challenge to be tackled, then blood flows to your heart and to your brain, and you experience a brief but energizing spike of cortisol.”
Meditate: we all hear about how good meditation is for you, but did you know it’s also been linked to – guess what – longer telomeres. In one study, researchers found carers of family members with dementia improved their telomeres with just 12 minutes of meditation a day.
Live in a close-knit community: Dr Blackburn points to emotional neglect, violence and bullying as all having negative effects on telomere health. So living in a tight-knit neighbourhood such as a retirement village could make a real difference.
Get married and keep your friends close: no surprise that marriage (although we assume only happy relationships) gets a big tick from Dr Blackburn for creating longer telomeres. Long-term friendships have also been proven to be beneficial.
And if you can, make lots of money: studies have also shown higher income influences telomere health.

Helping you find the right retirement or restcare facilities.
The team at Aged Advisor are locals that have first hand experience with Retirement Villages, Rest Homes and Aged Care facilities, either through our line of work (providing services to residents within these facilities) or by having family or loved ones living there. We do not own or run restcare or retirement facilities, and we do not own any shares (personally or as a company) in any Retirement Complexes or Groups - so we have no financial interests in these facilities. We simply want the best for the people that live there or are looking to make a decision of moving to one.
