A lunchbox for longevity

Thirsting for the fountain of youth? There is no shortage of tactics to live longer, or perhaps forever. Step number one: starve yourself…

Eating

“One must eat to live, and not live to eat,” wrote Molière, and the world of dieticians would tend to agree. Five to nine plates of fresh fruit and vegetables a day just about encapsulate the recommended diet for a lengthy life. Out go pizza, pastries, fried breakfasts and juicy steaks–all guilty of high cholesterol and “oxidative damage” to the body. Instead, bid welcome to broccoli (rich in antioxidants), bran (rich in fibres), steamed spinach and skinned chicken, rotated at one’s pleasure and served with skimmed milk. Of course there have been notable dissenters. David Henderson, a Scottish farmer who died aged 109 in 1998, swore by a diet of porridge, prunes and a mixture of cattle salts and gin. Other suggested elixirs include champagne and vintage port. Scientists, on the other hand, insist that all laboratory tests point to the same conclusion: the best way to live longer is just to eat less, much less. Undernourished, cold and terminally bad tempered animals, they say, generally live to a ripe old age.


Pill-popping

Enough of raw cauliflower and Chinese leaf treatments–the busy Western consumer wants long life, and wants it before breakfast. Acutely aware of the market interest in user-friendly longevity treatments, researchers have been sifting through the potions. Top of the list at the moment is Dehydroepiandrosterone, or DHEA for short, a hormone produced naturally in the body by the adrenal glands, and that later transforms into oestrogen and testosterone. According to its disciples–and there are many–use of this drug can tighten skin, firm up bones and transform sex without a murmur of complaint. Unfortunately the evidence is limited, the influence on the liver and other organs unknown, and the usual perverse effects of hormone replacement (breasts for men, beards for women) as present as ever.

Additives

“Oxidative damage” is caused when cells in the body fail to process food efficiently and instead churn out molecules that oxidize the body–much as metal rusts, the flesh sags and genetic material withers. Vitamins A, C and E come highly recommended, as does beta carotene. Gingko, Ginseng, Bilberry, Soy Lecithin and Hawthorn leaves each have their supporters. Similar miraculous claims have been made for onions and garlic, which can either be taken raw, crushed into oils, served in juices or soaked in alcohol for over a week to produce an aromatic tincture. Taken together, this course of curative infusions is guaranteed to keep the doctor away.


Going genetic

But why stop there? Who says evolution and its army of tight-fisted genes should get in the way of immortal gratification? Now that the human genome has been plotted, numerous scientists believe the average life span can be stretched to 100 or 120.
Tissue engineering, laboratory generated organs and therapeutic cloning have all been proclaimed as the next great breakthrough. In particular, much is expected of stem cells that can fill in for wasted neurons, bone marrow and tissue. And if that doesn’t do the job, there are always alternatives.
How about freezing your brain upon death and waiting around for a lucky break? Or what about porting into a computer or well-oiled robot? But if neither the vat nor the android tempts you, there is still some consolation: as Jorge Luis Borges wrote, the immortals lead numbingly empty lives, for like animals they have no consciousness of death. “It is divine, terrible and incomprehensible to know one is immortal,” he wrote.
