I was intrigued to read about open-water endurance swimmer Diana Nyad and her dream of finally completing a 103-mile swim from Cuba to Florida at age 60. The feat eluded her when she tried to accomplish it 32 years ago.

Back then, jellyfish stings, a badly swollen tongue and rough waves forced her to quit after nearly 42 straight hours in the water, 80 to 85 miles short of Key West. Nyad--who has gone on to have second and third acts as a TV and radio sports reporter and commentator and as a web-based fitness trainer--no longer has the incentive of trying to accomplish an unprecedented feat (former Australian distance swimmer Susie Maroney conquered the Florida Straits in 1997). This time her motivation is to make a statement about age and human potential.

It was only a matter of time--the same geo-tagging technologies that help make social networks so popular are now being harnessed to help adults with the task of caring for aging parents. Web-enabled sensors can send info as simple as what time someone got out of bed to more complex medical stats like real-time blood pressure readings. Is this a godsend, or Big Brother run amok? The New York Times explores the issue.

Dental implants are emerging as a popular alternative to dentures when it comes to tooth replacement. Though they may be easier on the mouth and last a lifetime, they can be murder on the bank account.

Happy birthday, Neil Armstrong! The first man to step on the moon ("One small step for man, one giant leap for mankind...") turns 80 today, and who's among the many well-wishers? None other than the Voice of Russia.

Also recently hitting the big 8-0 is choreographer Paul Taylor, who championed and transformed modern dance. Ever a rebel, Taylor smokes, drinks and, yes, still dances. There's a lovely tribute to him in The Wall Street Journal.

Are baby boomers creating a bubble in the rare gold coin market?

One thing older Americans are helping to power is a boom in bus travel. With gas prices on the rise and bus companies rolling out snazzy new coaches, savvy travelers are increasingly leaving the driving to someone else.

It turns out all sugars are not created equal: Cancer cells are crazy about fructose.

Maybe you've retired, or maybe you're running that brand new business from your garage. Either way, you're home a lot these days. What's one of the most important words in your vocabulary? According to The Wall Street Journal, it's "No," and you should be saying it to the many people clamoring for favors.

Here's an entertaining back-and-forth from across the pond: An essay in the Guardian that says, basically, baby boomers ruined the world, is followed a few days later by a spirited oh- no-they-didn't rebuttal. Your thoughts?

The U.S. Food and Drug Administration gave the go-ahead last week to Geron, a Northern California-based biotechnology company, to begin clinical trials of GRNOPC1, an embryonic stem cell treatment for paralysis.

Patients at seven medical centers around the country will participate in the research, which should begin in a month or so. It will be the first-ever trial of embryonic stem cell therapy on humans, and it's a development that could have a potential impact on the health of aging boomers.

The latest debate over the massive health-care overhaul passed by Congress this summer: Can it keep Medicare alive? According to Kathleen Sebelius, who heads the U.S. Department of Health and Human Services, the answer is a resounding "yes," with the program looking robust through 2029. But (you knew that was coming, right?) some critics claim she's cherry-picking the details. Here's a smart analysis in The Wall Street Journal that lets you draw your own conclusions.

Great news for people living with diabetes: Researchers have developed a wireless sensor that can be implanted in the body and automatically monitors glucose levels. The first human trial begins this fall.

Despite years of decline and more decreases predicted for the future, the outlook for American manufacturing jobs isn't all bleak, especially for older workers.

An aging workforce in manufacturing industries and projected growth in specialized manufacturing inside U.S. borders will lead to more opportunities, both on the factory floor and in white-collar and management positions, according to industry watchers.

In director Rob Reiner's 2008 comedy The Bucket List, Jack Nicholson and Morgan Freeman portrayed a pair of men who discover that they are dying, and then decide to fulfill checklists of experiences and accomplishments that they want to have before their lives are over. The movie was a huge hit, in no small part because the concept of making a checklist of things to do before one dies seems to really resonate with people, particularly boomers.

In a recent speech at the International AIDS Conference in Vienna, for example, former President Bill Clinton told listeners that he actually has two bucket lists. The B-list includes feats such as running a marathon and climbing Africa's Mount Kilimanjaro, things that "would be fun to do but doesn't amount to a hill of beans whether I get to do it or not." His priority A-list, in contrast, includes living long enough to see his daughter Chelsea have children. Beyond that, the former President would like to see a day when "all the grandchildren of the world will have the chance in the not-too-distant future to live their own dreams and not die before their time."

Remember when the Toyota Prius was the only green car in the game? Ever-spiking gas prices and a car-buying public eager to live green have put an end to all that. This summer, with a Honda hybrid sports coupe making a splashy debut and Chevrolet taking orders for it's plug-in hybrid, the Volt, the pedal's to the metal on the eco-autobahn.

Chevy's Volt, powered by batteries and backed up by a gas engine, comes with a price tag of $41,000. (Tax credits take the total down a bit.) The Volt takes 10 hours to charge, then has a range of about 40 miles before the back-up engine has to kick in. Unlike previous electric cars, which had to be re-juiced at the socket when they ran dry, the Volt's back-up gas engine (which makes electricity) means drivers won't be left high and dry.

They say with age comes wisdom.

I say with age comes clutter--tax returns, bank statements, receipts and paid bills that can pile up unnoticed until they're spilling out of drawers and closets.

Whether you're married or single, if you're over 40, you've had decades to accumulate a daunting paper trail.

Here's the good news--older entrepreneurs have a better shot at success than their more youthful colleagues. So what's the bad news? It's not so much bad as challenging: With the internet now integral to so many startups, it's critical for boomer business owners to learn how to protect their reputations online and remain vigilant about it. And yes, there's even an acronym for that--ORM, or online reputation management.

When former Wall Street Journal writer Jeff D. Opdyke left the newspaper after 17 years, he decided to go after his true passion--international investing. But as he explains in his newest column (seriously, you thought a newspaperman could ever really quit the biz?), the road to a dream job is paved with hard work.

Lisa Johnson Mandell couldn't understand why the entertainment industry jobs she applied for kept going to younger, less-qualified people.

But when she showed her resume to her husband, he spotted the problem right away: On paper she looked old. The long list of experience dated her. So did the bad perm and frumpy clothes in her resume photo.
