Pill that adds 30 years to your life

LONDON: It has been the ultimate goal of alchemists and sorcerers for centuries - the ability to increase one's lifespan. Now Scottish scientists say they have unlocked the secret to an elixir of life.
According to Scottish daily Scotsman, a pill by Aberdeen University professor John Speakman, if taken once a day would keep a person healthier, able to work longer and would also extend age limit by up to 30 years.
Medieval alchemists had earlier tried in vain to make an elixir of life by dissolving gold in different liquids, while ancient Egyptians believed they could harness the power of the earth to create the Aqua Vitae.
But Speakman has identified a more realistic candidate - a hormone called thyroxine.
According to him, by altering the crucial biological process called metabolism, it is possible to reduce damage linked to ageing inside animal cells. "If you increase the metabolic rate of a mouse then it increases its lifespan," he said.
This idea of metabolising fast and dying old turns traditional scientific thinking - which assumes an animal's lifespan depended on the amount of energy it burned up - on its head.
Speakman claims the normal metabolic cycle that occurs every time we breathe results in highly reactive, toxic molecules of oxygen called free radicals that damages the DNA and other essential building blocks - resulting in the ageing of body tissues.
According to him, animals with faster metabolic rates actually produce fewer harmful free radicals. By creating drugs to replicate the effect, it would take longer for the damage caused by free radicals to occur, he said. "Because free radicals also play a role in causing cancer and other diseases, reducing the number produced can not only increase the length of time someone lives but increase their healthy lifespan," Speakman said. "We found making the metabolism in cells less efficient meant fewer free radicals were produced. In effect, a pharmaceutical target would pump up the metabolic rate to reduce the free radical production.
"We could see people retiring at the age of 80, so they will be productive for much longer. The social and economic impact of that would be profound," he said.
Speakman, who is set to reveal details of his research during a lecture at the Edinburgh International Science Festival, has already attracted backing from powerful players in the scientific community. He has been given a grant of 450,000 pounds by the Biotechnology and Biological Sciences Research Council to find a drug to stave off the effects of old age.
Over the next four years, Speakman and his team will examine the effects of thyroxine on mice to see if it helps them live longer. They also intend to look into what stage in life people would need to start taking the drug.
But he warned it could be at least 10 years before a drug finally reaches the market.

I dont know why anyone would want to live 30 years more. If I were 'destined' to die around 70, then if i take the drug, i will live up to 100. I can hear my great grandchildren cry, "who asked him to take the drug?" and then curse the inventor.

Recently saw a story in the news about monkeys being studied for "looks" and longevity. Scientists are leaning towards the belief that it is better to eat less than eat and burn the calories by metabolism. Lesser you eat (NOTE: not starve) slower the aging and greater the longevity.

Hair now, gone tomorrow!

  Today, my husband was pleasantly surprised when he called out from the bathroom for a shampoo bottle. Normally, this would prompt a tirade about his laziness, followed by my hurried hand off of our regular brand of shampoo. But today, I handed him expensive bottles of shampoo and conditioner with a smile, saying, “With love.” Though puzzled, he was happy to indulge in the fancy products. I quietly slipped away before he realised they were the result of one of my hair care experiments gone wrong. Since moving into our new home, my obsession with hair care has reached new heights. Hair loss is such a rampant problem in my community that it’s probably the only topic people don’t argue about in our WhatsApp group. In a desperate attempt to save what’s left of my hair, I’ve tried everything: onion shampoo, rice water conditioner, WoW serum, Adivasi hair oil—you name it, I’ve tried it! Adding insult to injury, my mother delights in reminding me, “You used to have such thick hair I ...

Enough, Just as You Are

“Hey, you’ve put on weight since the last time we met!” This isn’t an uncommon greeting from one of my friends. Trust me, he doesn’t mean to hurt—but somehow, he always does. He’s not a mean guy; in fact, he’s one of those friends I can call in the middle of the night for help. But that’s just his way of talking—not just with me, but with everyone. I’ve tried explaining to him that this sort of comment is body shaming and that it’s neither kind nor funny. But he just waves me off, insisting it’s all harmless fun. The truth? He’s far from alone. Comments like these are ingrained in our everyday conversations, especially among women. Often, they come from people who claim to mean well. Think about it—how many times have you heard a relative or a friend casually drop a remark like, “Your dress seems tighter. Gained weight, huh?” For me, it’s my aunt. She never fails to greet me with, “Enna nalla sappadare pole irukke?!” (Translation: “You seem to be eating well!” ) I know she do...

Thirukkural: Short verses, long forgotten

Thirukkural —this two-line wonder—has been an integral part of our lives in various forms since childhood. Yet, I hadn't picked up that small book in a long time, except when my husband asked for the meaning of a Kural quoted by a politician in a speech or recited by finance ministers during Budget presentations. (I’ve always wondered why quoting Thirukkural has become a ritual, even for finance ministers with no connection to Tamil Nadu!) That aside, my interest in this seven-word marvel was recently rekindled by The Times of India initiative, where famous personalities share their favorite Thirukkural . As I listened to their experiences, I was surprised at how many Kurals I could recall effortlessly, despite never having consciously studied them. In school, I was a Sanskrit and Hindi student, so my Tamil lessons never came from textbooks. Yet, my love for Tamil never faded—thanks to my father. He always had a Kural ready for every situation, and perhaps that’s how I pick...
