A
growing number of Americans are living to age 100. Nationwide, the
centenarian population has grown 65.8 percent over the past three decades, from 32,194 people who were age 100 or older in 1980 to 53,364 centenarians in 2010, according to new Census Bureau data.Jan 7, 2013

People also ask
How many people in the world are over 100?
The United Nations says that by 2050 there will be 2.2 million people in the world who are over 100. That is as many people as the entire population of Houston. The figure for the number of humans aged 100 or older in the world today is about 300,000.Jul 12, 2011

Feb 23, 2016 - Even
further back, in Greek mythology, ambrosia granted eternal life. We're
still searching for ways to hit the biological pause button, but today's
scientists have a more practical approach: They hope to stall aging to
prevent the diseases that so often come with it. If they succeed, we'll
not only live longer, we ...

How To Stay Young And Healthy
Scientists target cellular breakdown in the war against aging and disease
Stay fresh

Some experts on
aging think we’re at the cusp of a medical revolution. The current model
for treating diseases such as cancer, diabetes, Alzheimer’s, and
cardiovascular disease is to attack each as they pop up. It’s a game of
healthcare Whac-A-Mole that might help people live longer but at great
cost to their quality of life. A new approach tackles the key risk
factor in all these illnesses: age.
“Once you are broken, it is hard to put you back together,” says Brian Kennedy, a molecular biologist and president of the Buck Institute for Research on Aging in California. “If we can target aging, then we can extend human health span, keeping people disease-free and high-functioning.”
That would give people more time when it matters most—when they’re feeling youthful enough to enjoy it.

Cell Service
Aging starts in a fundamental part of our bodies: our cells. Scientists have identified several processes that all play a role in how cells break down.Cut short
The end of each chromosome is capped with a protective bit of DNA called a telomere. As a cell ages, the telomere shortens; once it reaches a critical length, the cell stops dividing.Zombie cells
Some cells enter a state called senescence—they stop dividing but resist death, producing inflammatory signals that harm healthy tissues.Trash pileup
Cells normally perform autophagy, eating up damaged proteins and other debris. But eventually this process jams up and trash overwhelms them.Failed assassins
In order to delete damaged DNA, cells go through apoptosis: programmed death. But some older cells don’t actually die, possibly one cause of cancer.Factory halt
Many organs contain adult stem cells that help regenerate and repair damaged tissues. But as we age, they can cease functioning or dwindle.Shaky genes
DNA constantly faces damage, both from internal glitches and external influences. Over time genetic casualties pile up, and our cells can’t repair them.Over and out
In 1961, cell biologist Leonard Hayflick showed that human fetal cells kept in the lab divide only a certain number of times before they die. The so-called Hayflick limit seems to play a role in cellular aging, but it’s not yet clear how. Some cells, such as cancer, can circumvent the limit and divide indefinitely—possibly via an enzyme that prevents telomeres from shortening.Take It From Me, 107-Year-Old Pauline Angleman

I was born on
October 4, 1908. I grew up on a farm with the biggest red barn in
western Oklahoma. The farm life is a good life—you eat better, get up
earlier, work, and play. You get fresh air and you walk all the time;
you’re not always riding something. It was a healthier life, I think,
than most people live now.
People just need to use their common sense and don’t overdo on everything. As my grandma used to say, be like the woodpecker and use your head. Don’t overeat. And lay off all these doggone carbonated drinks. I eat two meals a day and snack a little in the middle. I drink lots of water—it keeps your innards lubricated—and I don’t have many wrinkles on my face.
I think it is so important to enjoy what you have. You can kill yourself worrying or being envious or just plain ungrateful. And worry is what brings on illnesses like cancer and heart problems.
Every age has been my favorite. I’ve had my picture taken so many times, you could paper the White House with it. I have a few aches and pains, but not enough to stop me yet. I have a red Chevrolet Malibu Maxx and my driver’s license is good until 2018. Neighbors tell me I’m going to wear out my garage door. —As told to Jennifer Bogo
