Secret no.18 Monogamy

Linah Mmola was born in Limpopo and apparently turned 117 years old recently in Tembisa, South Africa. I say ‘apparently’ because there is some debate about Linah’s birthday: her family believe it was January 2nd 1898 but there are (perhaps understandably) no documents to prove it. Whether Linah is 117 or a little younger, though, there is little reason to doubt she’s lived a very long life. Her secret? Well, she told the local Eyewitness News that her longevity was down to ‘staying true to one good man for many years‘, as well as a diet of spinach and corn meal porridge.

At least we think she did’: it’s not clear from the reports whether Linah gave this reason or one of her family.

But let’s assume she did say it: could it be true?

Plausibility rating: 5 out of 10We know (see Ways to Live to 100 no. 12) that loneliness and isolation can be bad for us but it’s a big stretch from there to concluding that monogamy is good for us. There is some academic research to suggest that marriage might be beneficial. One 1995 US study called, perhaps inevitably, ‘Til death do us part‘ found that married people had longer lives than single people. However that in itself does not mean that monogamy leads to a longer life. For one thing, married people are not necessarily monogamous, as the data leak from the AshleyMadison website this month reminds us. Nor can marital status at time of death – which many of the studies use – distinguish between lifelong pairings and deathbed dalliances. Finally, it’s also possible that those in good health are more likely to get married in the first place, rather than it being wedlock that leads to healthiness. There is an entertaining run-through of other possible health benefits of marriage here. However when a link about married women takes us not to an academic text but at a Beyonce video we know that we are on shaky ground.

For the opposition, one lovely  piece of research by the University of Sheffield bangs the drum for polygamy. It found that men aged 60+ from countries that practice polygamy lived on average 12% longer than men from mostly monogamous nations. ‘Want to live longer? Get a second wife’ said the New Scientist while the Daily Mail found an expert to say that men in polygamous marriages ‘benefit from having a fuss made over them by a gaggle of women’ as well as being better cared for into old age.

While that may not be conclusive proof (not least because it tells us nothing about the longevity of women in polygamous marriages – or the longevity of men and women in polyandrous marriages, for that matter) it is enough to conclude that the case for monogamy and long life is, at best, not proved.

Secret no.17 Guinness

Gladys Fielden has been drinking a bottle of Guinness every morning at 10.30 and reckons it’s the key to her having reached 100. She told the Daily Express: ‘They say it’s good for you and it’s certainly done something for me‘.

Gladys started drinking Guinness when she was pregnant with daughter Linda. She now has two grandchildren and three great-grandchildren. One of the grandchildren, Michelle Clews, says: ‘I’ve always known her to drink it. She’s always believed it’s what keeps her healthy. Gladys is very stubborn in her ways and she’s got to have her Guinness. If anyone in the family is ever ill she tells them to get a Guinness down them.’

Whether it’s the Guinness or not, Gladys is not just long-lived but has also stayed healthy and active. She only gave up baking when she was 90. Says Michelle: ‘She’s a remarkable woman and very good for her age. I think we all hope we can be like Gladys if we get to her age.”

Plausibility rating: 5 out of 10Guinness had stopped using it’s famous slogan in Britain by the 1980s (though it continued in use in Africa and some other countries until the 1990s when – with a nudge and a wink to the belief that it was good for the libido – it was replaced with ‘Guinness: the power’). Whether because of the slogan or not, belief that it was in some way medicinal and – in particular – was a good source of iron has prevailed: a free pint of Guinness after donating blood was only ended in Ireland in 2010. We’ve already seen (Ways to live to 100, number 2) that alcohol in moderation is generally associated with longer life (albeit with some reservations) – but is Guinness any better for you than other alcohol? Well, just possibly. Researchers at the University of Wisconsin found that dogs given Guinness had less blood clotting than those who drank lager – an effect similar to aspirin. It is also surprisingly low in calories compared to most other beers. On the other hand, it’s not a good source of iron: you’d need to drink 15 pints of Guinness (definitely not good for longevity) to get the same amount of iron as there are in two Weetabix. And – sorry Gladys – not many doctors would recommend drinking in pregnancy these days. So, all in all, Guinness is probably good for longevity in moderation – but no more than other alcohol. That’s not much of an advertising slogan though, is it?

Secret no.16 A good doctor

3373106750_2ddd4772d9Centenarian Lilian Grundy doesn’t think she’s particularly old – she has an older sister-in-law in Australia who’s 104 and a younger sister who’s also still going strong.

Her life has taken in running a fish and chip shop, being a Citizen Advice Bureau adviser and – during the war – seeing a doodlebug hit her home town, Oldham. Her husband, Harry, died in 1970 and Lilian has no children.

The key to her longevity, she thinks, is being able to follow good medical advice: “I must have a good doctor. I think my secret really must be that I do what I’m told. If the doctor tells me to do something, I do it.”

So, is she right about her doctor being the key to her long life?

Plausibility rating: 7 out of 10. At first it seems obvious that medical care has played the most significant role in increasing life expectancy but in fact it’s a surprisingly contentious claim. Some historians argue that it is public health issues – clean water, better housing, the decline of smoking, safer food, workplaces and homes – that have played the larger role. Certainly life expectancy grew rapidly in the 19th century, ahead of the great medical advances of the 20th century such as antibiotics. And there were marked falls in life expectancy, particularly for men, from 1914-1919 and 1939-1945 so clearly non-medical factors have played a role too (think of that doodlebug from Lilian’s life history). In fact, one thorough study of the subject credited medical care with just 50% of the increase in life expectancy since 1950.

But what we’re interested in is the growth in the number of the oldest old and especially those who reach 100. Surely the main reason for the increase in centenarians is our ability to keep alive for longer people with multiple long-term conditions? Well, yes and no. A major study of Okinawans, who have more than twice the rate of centenarians of the US population, cites a range of factors that includes public health infrastructure, housing, income, and nutrition as well as access to better medical care.

So it looks as though Lilian’s longevity secret is part of the answer but not the whole answer.

Secret no.15 Water from a wishing well

3304915442_aa97907234_o100-year-old Thelma Arnold isn’t sure why she’s lived so long but she has a suspicion: she once visited a wishing well in Fort Lauderdale and drank two scoops of water. ‘I didn’t think it did anything, but here I am,’ she told her local newspaper. ‘For some reason, I’m still here’.

Tragically, though, this isn’t Thelma’s only brush with the supernatural. She recalls seeing her parents with her two-year-old brother and thinking: ‘I’ll never see him again’. He drowned the same day.

Thelma’s mother moved in with her for a while before passing away at the age of 83 and today her grandson lives with her. He is one of five grandchildren, five great-grandchildren and five great-great-grandchildren.

Thelma worked as a waitress and a shop assistant, walking to work for years until she passing her driving test at the age of 60.  She thought she’d failed: ‘I was riding along nice when the man said make a right turn and I made the prettiest left turn you’d ever seen. I pleaded poverty and he passed me.’

At 100, she remains mentally alert, reading the newspaper every day and still enjoying watching the TV (recalling that her father regarded the TV as ‘evil’).

Plausibility rating: 1 out of 10. There really is nothing remotely scientific that could support Thelma’s theory. To be fair, that’s as much as there is for homeopathy, which nonetheless supports a multi-million pound industry. But if we’re going to follow the evidence we have to mark this all the way down to one.

Secret no.14 Yoga

103-year-old Lil Hansen is clear that yoga is key to her long life – and not just practicing it. Every Wednesday, Lil drives to her local senior centre and leads 30 other seniors in their yoga class. As Vickie Collins, director of the Michigan centre, says ‘Reaching 103 is amazing, but reaching 103 and still driving and doing yoga is truly amazing.’

Lil herself is more self-effacing: ‘I make it up as I go,’ she says. ‘As long as they enjoy it, I will enjoy doing it. They’re not ready to get rid of me yet, so I have to stick around for a while.”

Her class has been running for 30 years, taking a break only last year as Lil recovered from a fall in which she broke her hand, knee and foot. She also credits yoga with helping her recover.

Plausibility rating: 5 out of 10. Lil is by no means alone in claming yoga as one of the keys to longevity. We can dismiss some of the more outlandish claims – of yogi who lived to over 200, or even 300, years old – but there is plenty of evidence that yoga has a positive effect on aspects of physical health such as balance and flexibility.

Practitioners of yoga also talk about effects on mental heatlh such as stress, depression and anxiety, and one study by Richard Brown and Patricia Gerbarg suggests that yogic breathing (pranayama) could potentially have a positive effect on factors associated with longevity. One 92-year-old yogi says ‘Take it from me, a regular, dedicated yoga practice is the key to a long and health life.

Overall, though, there’s surprisingly little hard evidence that yoga improves lifespan (more on this in a later post here). But here’s the thing: people don’t practice yoga because they want to live longer, they do it because they want to live better. If they get a few extra years, that’s a bonus. And, as we’ve seen before, having a motivation, any motivation – whether it’s taking a yoga class or teaching one – can be more important than its precise nature.

As Lil says of her teaching: ‘It makes me get up in the morning.’

Secret no.13 Bacon

1444659348_d8f95a9ccaWe’ve met the remarkable Susannah Mushatt Jones before, when she was quoted as saying that ‘sleep’ was the key to her longevity. But as she turned 116 on July 7th, and remained the world’s oldest woman, she apparently told a reporter that there was another factor: bacon.

Every morning, it’s reported, she has four rashers of bacon with eggs and a sign in her kitchen says: “Bacon makes everything better.”

So –  assuming she really did say it – is that the secret of a life that started in Alabama as one of 12 children picking crops, before moving to New York as a nanny?

Plausibility rating: 2 out of 10. Let’s be honest, bacon really is not the key. In fact there’s research to suggest that processed meats like bacon are actually a risk factor for longer life, not a likely way of achieving it. Most recently the World Health Organisation advised that 50g of processed meat daily was enough to increase the risk of colorectal cancer by 18 percent. That’s half of what Susannah’s been eating every day.

All in all, if you want to take Susannah’s advise her original ‘secret’ – sleep – is probably a better bet.

Secret no.12 A loving family’

Nazar Singh, who died last month in India where he was visiting family, was believed to be Europe’s oldest man. He was though to be 111, though he had no birth certificate.

He told media after his 110th birthday that his longevity was due to good food, good family and happiness. However his fondness for a tot of whisky every night – and perhaps the fact that he was pictured on his birthday with a pint of lager and a whisky chaser – led understandably to the whisky also being cited (we’ve covered whisky in another post).

Nazar was born in the Punjab, India. He navigated two world wars and the independence and partition of India before moving to the UK in 1965. He worked in a foundry in the West Midlands and then moved to Sunderland on retirement. He returned to India in January this year and was being cared for by his two eldest sons.

Plausibility rating: 8 out of 10. We don’t know exactly what food Nazar ate (though we know he drank milk and almond oil}. There is evidence about the beneficial effect of alcohol in moderation but also some that questions it. And he is surely right to emphasise the importance of a loving family to longevity: the absence of strong relationships – whether family or friends – is linked to early death. One study, cited by the Campaign to End Loneliness, says it is the equivalent of smoking 15 cigarettes a day. Nazar believed that ‘family need to look after elders’, a view that would be popular with the Health Secretary, Jeremy Hunt, who recently worried in public about the number of ‘lonely funerals’. The latter need not have concerned Nazar: he had 34 grandchildren and 63 great-grandchildren.
