Astonishingly, Iffrig was helped to his feet, apparently uninjured, and finished the race.

“I was heading for the finish line,” he told ESPN’s Steve Levy. “The shock waves must have hit my body and my legs just started going like noodles … I wasn’t unconscious … so I made an attempt to get up. As I did that, one of the assistants came over and gave me a hand, and walked me on over to the finish line so I could finish.”

Join the Discussion: Is there a common denominator connecting terrorist acts around the world?

“I wondered [if] it might be a terrorist plot, or something,” he told CNN’s Piers Morgan about the blast. “The way it went off, this big bomb going off … that doesn’t happen every day.”

Iffrig has run 45 marathons, according to the CNN report. After finishing his third Boston Marathon yesterday, he walked about six blocks to his hotel and was reunited with his wife.

His main concern? That this horrific crime would ruin the Boston Marathon. “Everyone else is out there having fun, and someone is out there trying to destroy the whole thing. Terrorists, or whoever they are, I just don’t have much use for it.”

Mr. Mayor
Zeitgeist Films/New York Post

“Ed Koch!”

The voice on the phone was not so much identifying itself as trumpeting an introduction. This was Ed Koch, all right, barging into our phone conversation with the same ebullience that characterized his three terms as New York’s most popular and controversial mayor since Jimmy Walker.

I caught up with Koch on January 10, at his modest Greenwich Village apartment. I can’t definitively say mine was the absolute last interview Koch granted before his death early on the morning of February 1. Heaven knows he loved to talk, and he was excited about a new documentary, Koch, that was to premiere around the country on February 1 (Yes, Koch, showman to the end, managed to hang on and breathe his last on the very day the film opened).

If you click on the link below, you’ll listen in on our chat, a great man’s valedictory, reflecting on how he’d like to be remembered. If you stick with it to the end, you’ll be treated to Koch quoting F. Scott Fitzgerald, writing in The Great Gatsby about the view of Manhattan from the Queensboro Bridge. Last year the century-old span was renamed in Koch’s honor, and you can almost feel the chill of pride that ran down his spine whenever he thought about it.

Here’s a link to blogger Patrick Kiger’s delightful recollection of Koch’s more memorable bon mots.

And here’s a link to Mayor Koch as my guest on the two-minute Movies for Grownups radio show, the episode that just happened to be airing nationwide on the day Ed Koch took that subway to the sky. By the way, don’t be put off by my joyful introduction about Ed Koch “still doin’ great!” He was at the time we spoke, for sure, and I have a feeling he’s now doing better than ever.

Ben Affleck, who charmed Barbara on the 2003 Fascinating People special, is well worth revisiting as he is now a doting dad of three and has a Barbara-licious Hollywood marriage with the lovely Jennifer Garner. Oh, and he’s directed a film in the Oscar mix, “Argo.”

Speaking of the Oscars, Barbara is talking to next year’s host, the very talented Seth MacFarlane. Also on the list, New Jersey Republican Governor Chris Christie whose outsized personality, is great TV — especially with his recent prominence before, during and after Hurricane Sandy, irritating fellow Republicans by daring to be seen publicly with President Obama, getting help for storm-stricken constituents on the eve of the election.  We have to wait for the show to find out who is number one, but we already know who is generating the most talk.

“A lot of people will say, ‘For heaven’s sake, this is ridiculous, this is a child at 5 or 6 years old entering beauty contests,’ ” said Walters, reveling in her Boo Boo controversy in Us Weekly.  “But the relationship between Alana (Thompson) and her mother —that’s the story, the two of them.  It’s very touching,” said Walters.  She also stressed, “Honey Boo Boo is not an obnoxious little girl” and talked about how sweet she is with her mom, sisters and baby niece who has three thumbs, “but so what?  It’ll make you smile.”  Who’d want to miss that?

As long as there are two parents together, they pretty much take care of each other,” said Francine Russo, author of They’re Your Parents Too!

Married couples can also take advantage of economies of scale when it comes to things like housing or insurance. Single seniors, on the other hand, lack both the emotional and financial support a spouse can provide.

According to Susan Brown, a Bowling Green sociology professor, unmarried older adults are “much more economically vulnerable” than married counterparts.

They’re more likely to be poor and to be using public assistance, and they’re less likely to have health insurance but more likely to have a disability,” Brown told Reuters.

When multiple marriages are involved, the situation could get even more tricky. Adult children may be called on to help care for stepparents as well as biological parents (and if both parents remarried and all parents and stepparents are still living, that’s quadruple the caregiving!). Or they may have to share tough caregiving decisions with stepsiblings they hardly know or trust.

Such issues will only multiply in the coming years. While there are obviously many boomers whose parents are divorced, the numbers are nothing compared with the number of divorced boomers themselves.

Since 1990, the divorce rate of those over 50 has doubled,” says Brown. “In 2010, the number of 50-plus divorcees was around 643,000.”

According to a study published this spring in The Gerontologist, one out of three boomers is currently unmarried, and some 60 percent of unmarried boomers are divorced.

“As soon as you have an inkling that a divorced parent might need assistance, it definitely requires a family meeting,” advises Joy Loverde, author of The Complete Eldercare Planner. “Everyone needs to be there, to open up about any concerns, to start sharing responsibilities. Start talking about it right now; do not wait.”

 ・Excess carbs linked to cognitive decline. In a three-year study conducted by the Mayo Clinic, high intake of carbohydrates and sugar was associated with higher risk of developing dementia. Lead researcher Rosebud O. Roberts said one reason is the effect of these foods on glucose and insulin in the brain.

 ・New retirement saving limits for 2013. The IRS announced last week that it would raise the contribution limits for IRAs and 401(k) plans slightly. In 2013, workers will be able to put up to $5,500 into an IRA and $17,500 in a 401(k) account. The additional amounts for those over 50 — an extra $1,000 for IRAs and $5,500 for 401(k)s — won’t change.

 ・McCain ’08 to Obama ’12 voters skew older, white and male. Of voters who backed John McCain in 2008 but now support Barack Obama, 55 percent are male, 34 percent are 55 or older and 72 percent are white, according to a new Reuters poll. Defectors to Obama made up a smaller subset of those polled than Obama ’08 voters who now support Romney.

Across social media outlets, the presidential election is straining previously friendly digital relationships. According to a survey from the Pew Research Center’s Internet & American Life Project, nearly one-fifth of people admit to blocking, unfriending or hiding someone on social media over political postings. [Only one-fifth???] The biggest complaints were someone posting too frequently about political subjects, posting something a user disagreed with or found offensive and arguing about politics with the user or someone they know.

“In the real world, we navigate these issues all the time,” Aaron Smith, a Pew research associate, told CNN. “We know not to bring up politics around certain friends or family members. We try to avoid people who are constantly looking for an argument or trying to sell us on their pet ideas.”

Since blocking, unfriending, hiding people is the closest social analogue to those real-world examples, it’s not necessarily surprising to see people taking these steps in the virtual space,” he added.

For some, the no-talking-politics mandate carries over from real life to the digital world: 22 percent say they avoid making political comments on social media sites for fear of offending others.

Among the Center’s other findings:

• 38 percent of users said they discovered through friends’ social network postings that their political beliefs were different than they thought.

• The majority of people users’ blocked, unfriended or hid because of politics were “distant friends or acquaintances”  in real life, not close friends, coworkers or family members.

So how about you guys — ever blocked, unfriended or hid a social media friend because of their political posts? And, if so, why?

• Democrats, Republicans differ in TV preferences? According to TiVo, they do. A study conducted by the company’s research and analytics division measured the top 20 shows for registered Democrat and Republican viewers — and not one network show appeared on both lists. Two of the top shows for Republicans were PGA golf tournaments and NASCAR, and reality shows were also popular. On the Democrat list, sitcoms and animated comedies scored high.

• Social Security increase for 2013 will be small. The cost-of-living adjustment for next year won’t be made official until tomorrow, but it’s expected to be between 1 and 2 percent — a raise of about $12 to $24 per month for your average retiree. “The COLA continues to be very critical to people in keeping them from falling behind,” says David Certner, AARP’s legislative policy director.

And while it makes sense that booze would take more of a toll on older adults than the younger set — after all, they’ve got quite a few more years of drinking under their proverbial belts — the magnitude of the cost difference is what’s startling: Alcohol-related hospital admissions for 55- to 74-year olds cost 10 times that of 16- to 24-year-olds. The number of older patients admitted for alcohol-related problems was about eight times higher than the number of younger patients admitted.

The report, from the UK’s national agency on alcohol misuse, found that overall alcohol-related hospital admissions cost England nearly £2 billion in 2010-2011.

Agency chief Eric Appleby said it’s a “common perception” in England that young people are responsible for rising alcohol treatment costs, but “our findings show that in reality this is not the case. It is the middle-aged, and often middle-class drinker, regularly drinking above recommended limits, who are actually requiring this complex and expensive NHS care.”

In the most recent study in the United States, the Centers for Disease Control and Prevention estimated that “excessive alcohol consumption” cost the country about $223.5 billion in 2006. This study, however, looked at a range of alcohol-related costs, including the somewhat nebulous cost of “losses in workplace productivity.” Only 11 percent of that total cost figure was from alcohol-related health care expenses.

This type of genetic testing — known as whole genome sequencing — has many useful applications. But medical ethicists worry over how, when and with whom such info may be shared. A report released today by the presidential bioethics commission reveals that many legal issues surrounding genetic privacy have yet to be addressed.

It is not a fantasy to think about how, in the future, without clear baseline privacy protections people could use this in ways that are really detrimental,” Commission Chair Amy Gutmann told the Associated Press.

“The life-saving potential of genome sequencing depends on gathering genetic information from many thousands (perhaps millions) of individuals, most of whom will not directly benefit from the research,” said Guttmann in a press release. ”Those who are willing to share some of the most intimate information about themselves for the sake of medical progress should be assured appropriate confidentiality, for example, about any discovered genetic variations that link to increased likelihood of certain diseases, such as Alzheimer’s, diabetes, heart disease and schizophrenia.”

At present, only about half of states make “surreptitious commercial testing” illegal. This means that, theoretically, anyone with access to your hair, saliva or snot could have your DNA analyzed, for whatever purpose. Right now, the process costs too much for such abuse to be likely; but with the price of gene-mapping dropping rapidly, it could soon cost less than the cost of many standard diagnostic tests.

Other protections are similarly spotty. For instance, a 2008 federal law prohibits employers or health insurance companies from discriminating on the basis of genetic information — but says nothing about life insurance of long-term care insurance providers.

The commission offered recommendations for “what ethically ought to be done and what legally must be done,” including:

• Improved data security and access to databases
• Integrating whole genome sequence data into health records
• Federal and state laws that ensure “a consistent floor of protections” covering genetic data “regardless of how they were obtained”
• Policies that prohibit unauthorized whole genome sequencing without an individual’s consent

Thursday Quick Hits:

• Who are you calling a tech novice? Forbes columnist Larry Magid complains that it’s “stupid and insulting” to treat boomers as universally tech-challenged. “I’m a baby boomer — and so is Bill Gates, Steve Wozniak and the late Steve Jobs,” writes Magid. “It was my generation that invented personal computers. Many of us used CP/M, DOS or even Unix long before Macs and PCs had graphical user interfaces.”

• RIP, Alex Karras. The former Detroit Lions lineman and TV and film actor died Wednesday at age 77. Karras had kidney disease, heart disease and stomach cancer, according to his family. His most well-known ailment, however, was dementia, which Karras attributed to old football injuries; he was one of the more than 3,500 former NFL players suing the league.

• Aging without children. In a beautiful New York Times essay, Kelly Flynn explains how her inability to have children has both shaped her approach to life and “taken on a different meaning” with age. “Now, as I help my parents navigate the trials and indignities of old age, I can’t help thinking, who will do this for me?” she writes. “Is it too late to cultivate a relationship, so that in my old age, there will be someone to sneak me a beer in the nursing home or care whether my socks match?”

News Interest: Overall, older adults expressed greater interest in news. Just 10 percent of boomers and 6 percent of the oldest group (ages 67 and up) said they’re “not really interested” in the news, compared to 23 percent of Gen X and 31 percent of the youngest group.** The percentage of adults in each age group who described themselves as “news junkies” hovered around 12 percent, with men nearly twice as likely as women to put themselves in this category.

News Attention Span: Older adults also seem to pay closer attention when reading the news (online or in print). Though less than half of all respondents either read every word of an article or skim full articles, those 67 and older were more likely than other age groups to do so. And while 11 to 12 percent of Gen X and Y respondents say they read headlines only, just 5 percent of boomers and 2 percent of the oldest respondents said they’re in this habit.

With the expectation being that online news will further displace TV over time, incorporating online news consumers’ habits and predilections into reporting will be increasingly important,” said Jill Gress, vice president of Harris Poll Insights.

“This means concise reporting, given online news consumers’ stronger tendency to read articles more selectively,” she continued, “and increased use of supporting data, as online news consumers are much more interested in this than those preferring TV.”

News Mode: Of all respondents, 36 percent said they preferred online news, 50 percent preferred TV news and just 10 percent preferred print news (alas!). Respondents 67 and up were most likely to choose print as a preferred news source (22 percent versus 13 percent of boomers, 7 percent of Gen X and 5 percent of Gen Y).

News Bait: Asked what enticed them to read an online or print article, 54 percent of respondents said a catchy headline does it; 44 percent said an interesting picture, 43 percent “interesting data or research,” 28 percent “an interesting infographic,” and 13 percent “who the author is.” The oldest respondents were most likely to be drawn in by pictures and data or research; the youngest group was most likely to be drawn in by infographics.

** Harris called the youngest group “Echo Boomers,” though this generation is more commonly known as the Millennials or Gen Y, which are the terms I’ve used. The age breakdowns Harris used for the youngest two generations are also atypical, with 18- to 35-year-olds considered Gen Y and 36- to 47-year-olds considered Gen X.

Wednesday Quick Hits:

• Don’t call it a commune. Cohousing is gaining popularity among retirees, but the movement is only tangentially related to hippie-era communal living. Cohousing emphasizes privacy but with social contact among members, advocates say. Residents live in private homes but share certain facilities (gardens, courtyards) and often weekly meals. “What’s the best thing about cohousing? We know our neighbors really, really well,” said Joani Blank, 75, a former board member of the Cohousing Association of the United States. “What’s the worst thing? We know our neighbors really, really well.”

• Boomers driving up urban rents? Yes, say some experts — though boomers aren’t alone in the blame. The trend among both recent retirees and recent college graduates toward renting over buying and urban over suburban living is pushing up city rents, they say.

Why? For starters, the scope of this study only included tests for expired drugs’ potency — not their safety.

“When the average reader reads this, the take-home message is not, ‘€˜Your expired medications are safe to take,’” warned lead study author Lee Cantrell.

What’s more, just because some ’expired’ meds may still be effective doesn’t mean yours necessarily are. All of the drugs tested in the study were in bottles that had never been opened. And the types studied — mostly painkillers and sedatives — are obviously quite different than, say, cholesterol medicine or antidepressants. While neither are likely to become toxic over time, they can become ineffective and ineffective medications can be just as dangerous if you rely on them for treatment.

But the study results could convince policy makers and/or drug makers that it’s time to take another look at certain drug expiration dates. Of the 14 compounds the researchers analyzed, 12 still fulfilled government requirements for potency, although they had officially expired 28 to 40 years earlier (the exceptions were aspirin and amphetamine).

“If manufacturers were required to do longer-term stability tests, it could be an enormous cost-saver for consumers,” said Cantrell.

Sixty-eight-year-old Barbara Miller Elegbede is one such full-time “couchsurfer.” After retiring from teaching and secretarial work, Elegbede began traveling the world, interspersing stays in hostels and hotels with free sojourns in strangers’ guest quarters. She finds the latter on couchsurfing.org, a web community with at least 160,000 members over 50. Notes Reuters:

Accommodations can range from a weathered futon in someone’s living room to a yacht bunk or a Maui tree house. Typical stays last two to three days but can also last several months. While you can reciprocate and offer your own couch when your host travels, there’s no requirement that you do so.
