Sex isn't just good for you, it might even prolong your life. Yesterday I described the latest cutting-edge science on how to slash your risk of disease and live longer.
Today, in the second extract from my new book How Not To Age, which looks at all the very latest research on ageing, I'm going to tell you how sex protects health and how age is no barrier at all to a fulfilling sex life.
We'll also look at how you can improve the function of the most important organ of the body - the brain.
As we'll see, Alzheimer's disease is very far from a genetic inevitability, and cutting the risk can begin right now.
Plus, I'll cover how to boost memory simply by tweaking your diet so you'll never again forget what you've just walked into a room to get (or at least,
정품비아그라 not so often).
I'm a doctor and bestselling author who's made it his mission to find the strategies that truly work to turn the clock back. So here's the cutting-edge science on sex and brainpower…

Having weekly sex cuts mortality risk by half >The science shows that regular sex really does appear to boost mental and physical health. In a study following more than 2,000 men and women for about six years, those with a higher frequency of sexual activity had a significantly lower risk of dying
>Those having sex 52 or more times a year - approximately weekly - seemed to have only half the mortality rate of those having sex once or less a year, even after taking into account other health conditions and age
>Why is that? Lots of reasons. Sexual activity releases feel-good chemicals called endorphins which decrease inflammation in the body and have been shown to improve the immune system
>Some researchers suggest sex prevents premature death because it's a form of exercise. Well, yes, but don't overestimate how useful your exertions are
>If a bout of sexual activity burned a couple of hundred calories, you might think, hey, I can get a side plate of chips with that. Trouble is, it doesn't. If you hook people up (literally and figuratively) and measure their oxygen consumption during the act, having sex turns out to be the metabolic equivalent of bowling. The average man might expend 21 calories during sex - not much more than he'd have spent watching TV on the sofa
>There is a stereotype that older adults are asexual, but this is ageist and inaccurate. In a 2016 study in England, 86 per cent of men and 60 per cent of women aged 60 to 69 reported being sexually active, as did 59 per cent of men and 34 per cent of women aged 70 to 79, and 31 per cent of men and 14 per cent of women aged 80 or older
>Generally, however, approximately half of older men and women report problems, most often low sexual desire in women and erectile difficulties in men. So what can we do about them

Lavender and apples boost libido for women>
Darker varieties of chocolate are better for you as there is less fat and sugar that counteracts the benefits of blood flow-boosting flavonoid
>
Is chocolate really the aphrodisiac that the Valentine's Day industry would have us believe?>The flavonoid phytonutrients in cocoa can help open arteries and increase blood flow - peaking at 90 minutes after eating - which in theory is good for women's sexual function. But make it as dark and as bitter as possible: fat and sugar in milk chocolate counteract the flavonoids' benefits
>Flavonoid-packed onions could also work very well - but the effect on breath might dampen the ardour. Luckily, there is a happy medium in… the humble apple. One Italian study found women who ate apples daily scored significantly higher on an index of overall sexual function than women consuming less than an apple a day - though researchers only counted women who ate unpeeled apples because phytonutrients are concentrated in the pee

What else can older women do to improve their sexual desire?</<br>
r>One is to eat soy-based foods. Studies show menopausal women who drink a cup of soy milk every day may have better sex - but be careful what you wish for. One 44-year-old went to her gynaecologist with an 'increase in desire that required her to self-stimulate to orgasm about 15 times daily', according to a case report. A month before she had started an almost exclusively soy-based diet, eating more than four pounds of soy food a da

The more orgasms for men the better - but only with their wives!
A study of men in Caerphilly, Wales, found that those with 'high orgasmic frequency' appeared to cut their risk of premature death in half - and, apparently, the more, the better. But not if you ch

Now get your brain into tip-top health
Dementia affects one in 11 people older than 65 in the UK, and 'benign forgetfulness', such as frequently misplacing your keys, is even more common - but it isn't inevita
Once it was thought that we lose brain cells as we age, but that's been proved wrong. In old age our brains have about 96 to 98 per cent as many neurons as we had when we were young. So how can we keep them healthy and reduce the risk of demen
Reduce salt. Increased stiffness of the arteries correlated with impaired cognitive performance in 14 studies - and it's a high sodium intake that causes it. We all eat too much salt, but cutting it by less than a teaspoon a day can significantly reduce artery stiffness, in addition to lowering blood press
Eat less meat, fried food, baked goods and processed foods packed with bad LDL cholesterol, which is associated with memory loss and brain disease. Humans appear to have evolved to sustain an LDL level of around 0.6 millimoles per litre of blood, but the average in the West is over 3 mmol/l. No wonder heart disease is the leading cause of death in higher income countries and dementia is killer number
Sleeping on your right side could 'drain' waste products from your brain more effectively, according to Dr Greger's
Sleep more but not too much. Fewer than seven hours a night is thought to increase your risk of cognitive decline, but so is more than eight or nine hours. Seven hours a night doesn't sound like enough, but it may actually be natural for our spec
