Tim Spector, a professor of genetic epidemiology at King's College London, is part of team behind the test. He says:'Studies have found that our blood's glycan levels closely track our chronological age'. In other words, different patterns occur at different ages - so how much you vary from the norm for your age is a sign you're ageing at a slower - or faster - rate than most of your contemporaries. Glycan patterns also change with the menopause because of the drop in oestrogen, which protects against ageing.
Three-quarters of women lose interest in sex after the age of 50 - but experts say there is no reason why you cant be having the best sex of your life.

Before filming starts, she does two to three months of dedicated training up to five hours a day. 'It's like a drug almost, you feel addicted,' Eva said. 'I go for a 30-minute run every day and do elliptical training [on a cross-trainer] and stretching.'
High blood pressure increases your risk of heart disease, stroke, heart failure and kidney disease. Now, three experts from the University of Newcastle, Australia reveal how to lower it. They say you should consume more rolled oats (top left) and vitamin C (top middle) to lower your blood pressure. People should also eat more beetroot (top right) as they cause the arteries to dilate, they say. But adults should avoid alcohol (bottom left) and liquorice (bottom middle) as they both increase systolic and diastolic blood pressure. However, caffeine should also be avoided because it increases blood pressure in the short term.
It helped Carola lose almost 100lb, but is this bizarre weight loss op a step too far? Expert describes the device as 'bulimia by surgery'
Three times a day, after each meal, Carola Karlsson from Sweden takes herself off to the nearest bathroom to dispose of a third of what she has just eaten to control her weight. But the crucial difference between this 43-year-old nursery nurse and someone with bulimia is that Carola 'purges' a specific amount via a surgically fitted medical device that drains food directly out of her stomach. Carola, who is 5ft 4in, weighed 19st before she had the device fitted two years ago. Within nine months, she had lost an astonishing 8st.
'As a child I was really scared of the water - I even hated taking baths': Olympic champion swimmer Adam Peaty takes our health quiz
From working out 35 hours a week to eating 8,000 calories a day, British Olympian Adam Peaty reveals how he trains for a major event. The swimmer has been diagnosed with hyperbolic joints, like Michael Phelps. 'I just push through pain when I'm training. If I don't feel it really burning when I train, I'm not doing it right, it's too easy,' he says. 'The hardest part is when I'm pushing my heart-rate so much that my heart can't work any harder.'
'The TERRIFYING bacteria I picked up in the jungle': Adam brought back a tropical disease from the Colombian swamps
Following a holiday in Colombia last year, Adam Millward woke up drained of energy and with a pounding headache. 'I knew it wasn't just a hangover,' says the 29-year-old from London. As he would later discover, Adam had leptospirosis - a bacterial infection that's spread through the urine of infected animals, such as cattle and rodents, and that you can pick up in contaminated water, practically anywhere in the world, including the UK.
Still unsure whether or not you should carry a donor card? Then read this young couple's devastating story
The only thing that saved Luke Yates from Hampshire in the horrible weeks and months after his wife Sam's death was the knowledge that she would have wanted him to go on living. When she died in his arms at the age of 28, his grief was so raw, so visceral that he thought he might lose his mind. Luke, a biomedical research scientist at Imperial College London, says he was 'haunted by terrifying flashbacks of the day she died, obsessed with the idea that I could have done more.
Family of baby whose head has swelled to twice its normal size 'sell everything they own' in a desperate bid to get her treatment
Nara Ariska (left), 10 months old, from a remote part of Indonesia, was diagnosed with hydrocephalus - a build-up of cerebrospinal fluid on her brain - when she was born, causing her head to swell (right). Her condition causes her headaches, nausea, vomiting, confusion and eyesight trouble. Medical officers in the village she originates from visited her family earlier this year and promised to pay for treatment to rid her of the disease. However, her parents are yet to see any action and have took matters into their own hands. In a desperate attempt to cure her of her suffering, the family have sold everything they own to raise funds.
The colour of cancer: Fascinating medical scans reveal what tumours look like under fluorescent lights and 3D scans
Collated by the National Cancer Institute, the images were taken at a number of cancer centres across the US. A range of fluorescent light micrographs, 3D transparent tumour tomography images and optical tissue clearing images were used in the collection. One scan shows cancerous cells lining the placenta (top left) and the intricate detail of a polyploid giant cancer cell in the breast (top middle), which is made up of different proteins. Bone cancer spreading to affect healthy tissue (top right) and a tumour which has grew so large it has exceeded the blood vessels ability to provide oxygen (bottom right) - a state known as hypoxia - can also be seen. Further images show breast cancer cells resisting treatment (bottom middle) and the proteins that allow cervical cancer to spread (bottom left).

Cancer-stricken teenager who was serenaded by Florence & The Machine in her hospice bed has died after five-year fight against bone disease
The 15-year-old cancer patient who dueted with Florence & The Machine in a viral video earlier this year has died. Karinya Chen, who battled bone cancer for five years, passed away in Austin, Texas. She touched millions of people around the world when she perfectly harmonized with the British Grammy-winning band while lying in her hospice ward in May. Just five days before her death on Saturday, she spoke with remarkable strength as she contemplated her disease. She said: 'I think the biggest thing is not to worry and fear.... You just have to remember that there's always tomorrow and if you take it one day at a time and just tell yourself don't worry and don't take things for granted and tell yourself that you are loved and you are blessed then it makes it a lot easier to fight.'
'I saw sex everywhere': How a brain tumor delayed this man's puberty - and rampant teenage sex drive - until he was THIRTY
Puberty makes everyone's teenage years a dragged-out nightmare. But at least we all going through it at more or less the same time. Imagine hitting that awkward phase in your late 20s. That is exactly what happened to E! News reporter Ken Baker - whose memoir is the subject of a new movie starring Jane Lynch: The Late Bloomer. Baker, now 46, experienced an almost unheard-of hormonal transition due to a benign brain tumor pressing on his pituitary gland. The tumor caused a hormone imbalance in his body called hyperprolactinemia, which over-produced the female hormone prolactin, stunting his natural development. It meant his body lactated milk from the nipples, 10 times more than a breastfeeding mother. His body was soft and lacking muscle. And he had absolutely no sex drive.
Nathan Box (left), seven, from Hornchurch, was struck down by a mystery illness two years ago - but doctors assumed it was epilepsy. However, a string of tests at hospital (right) revealed he was suffering from an incredibly rare brain tumour called Hypothalamic Hamartoma. The side effects of his condition means he breaks into a grin shortly before having a seizure - of which he can have up to 25 in a day. But the family were left heartbroken after the NHS refused to fund a miracle operation in the US. Instead Nathan will remain on drugs to lessen the symptoms for the rest of his life - not cure them.
Tariq Idrees, a dentist and owner of a private clinic in Manchester, advises people to drink through straws because the liquid bypasses the teeth. Here he reveals the quickest ways to stain your smile. He says you should avoid tomato ketchup (top left) because it's acidic and rich in colour and steer clear of ice lollies (top middle) which contain colourants which stick to the teeth. Fruit teas (top right) are rich in colour which leave surface staining while strawberries (bottom right) are high in their acid content. Any type of cola (bottom middle) is bad for staining teeth and chicken tikka masala (bottom left) contains a lot of turmeric which can easily stain teeth.

Student, 17, who suffers from rare skin condition causing painful blisters which leaves her looking like she has been 'mauled by a gorilla'
Lucy Beall Lott (left), 17, from Santa Fe, was diagnosed with recessive dystrophic epidermolysis bullosa (RDEB) when she was born. Her condition means just picking objects up can cause her fragile skin to shred off, leaving her with painful blisters and wounds (right). Whenever she swallows the skin in her throat is severely damaged - putting her at risk of choking to death. When she was 13, she had just a 3mm opening in her throat - forcing surgeons to stretch her skin in a complex procedure (inset). She's suffered hurtful comments from strangers including that she would be 'hot' if it wasn't for her scarred legs and arms throughout her childhood. Despite the vicious remarks, she's adamant she has nothing to hide since and refuses to let her condition hold her back.
Distraught mother claims her Down's syndrome son was turned away from a play centre after staff said it was 'unsuitable for children like him'
Simone Blount (left, with her son when he was a baby and right) took her four-year-old son Stephen to the Mattel Play! centre, Liverpool, for a day out. But she claims that, after queuing for more than 20 minutes, a female member of staff leaned over her desk to look at Stephen and said the centre was 'unsuitable for children like him'. She added that Stephen was 'absolutely heartbroken'. Mattel Play! (inset) deny the claims and insist a member of staff 'mistook' Stephen for a baby in a pushchair and was 'just trying to help'.
Candice Dent (left), 35, from Kentucky, suffers from aquagenic urticaria - which triggers an outbreak of hives (top right and bottom right) if she comes into contact with water. But she also suffers from dermatographia, meaning her skin becomes itchy and swollen when touched - which she said is far worse. It prevents her from wearing certain clothes and sleeping on certain materials because they will cause welts in her skin. Medication has proved to be ineffective, meaning all she can do when she has a break out is wait for the itchy hives to disappear.
'I'm a dinosaur loving 5-year-old, a Southern belle and a sex addict called Rogue': Woman, 24, claims she has 8 different personalities
Victoria Vega, 24, from California, has dissociative identity disorder which started during her troubled childhood. It results in her different personalities taking control of her body at any given time. These personalities include Southern Belle Allie, tough New Jersey gal Goldie, AGE, and dinosaur-loving Senka, 5. She also has quieter 'alters' Citizen, Lucy Lovelace and Celia. Miss Vega says she does not consider it a disorder and loves her different personalities which mean life is 'never boring'. She blogs about her experiences and has even written a memoir about her experiences with the condition. 'I hate to call it a disorder because I genuinely don't feel sick. I love my alters and without them, I promise I would not be here today,' she said.
