Research Suggests Older Mothers Likely Live Longer
Researchers believe women who have their last child after 33 are more likely to live into their late nineties. The findings are a matter of genes, meaning the relationship between late motherhood and long life is correlative, not causative.
What's the Latest?
Women who have their last children after the age of 33 may possess genes that allow them to live past 95, reports Lena H. Sun of the Washington Post. These findings are part of a Boston University study published in Menopause: The Journal of the North American Menopause Society. Thomas Perls, one of the study's lead investigators, told The Post about his team's conclusions:
“We think the same genes that allow a woman to naturally have a kid at an older age are the same genes that play a really important role in slowing down the rate of aging and decreasing the risk for age-related diseases, such as heart disease, stroke, diabetes and cancer.”
What's the Big Idea?
Sun goes on to explain the process by which these results were found:
The research found that women who had their last child after the age of 33 had twice the odds of living to 95 years or older compared with women who had their last child by age 29.
She also mentions Perls' insistence that the relationship between the two events -- late motherhood and a long life -- is one of correlation, not causation. Delaying childbirth can in fact increase the risk of birth defects.
Scientists will no doubt continue to research this topic and attempt to identify the genes responsible for this fascinating correlation. With genetic engineering increasingly being discussed as a key component of future family planning, it's easy to see long-life genes being a rather popular choice.

Antimicrobial resistance is growing worldwide, rendering many "work horse" medicines ineffective. Without intervention, drug-resistant pathogens could lead to millions of deaths by 2050. Thankfully, companies like Pfizer are taking action.
- Antimicrobial-resistant pathogens are one of the largest threats to global health today.
- As we get older, our immune systems age, increasing our risk of life threatening infections. Without reliable antibiotics, life expectancy could decline for the first time in modern history.
- If antibiotics become ineffective, common infections could result in hospitalization or even death. Life-saving interventions like cancer treatments and organ transplantation would become more difficult, more often resulting in death. Routine procedures would become hard to perform.
- Without intervention, resistant pathogens could result in 10 million annual deaths by 2050.
- By taking a multi-faceted approach—inclusive of adherence to good stewardship, surveillance and responsible manufacturing practices, as well as an emphasis on prevention and treatment—companies like Pfizer are fighting to help curb the spread.
Entrepreneur and author Andrew Horn shares his rules for becoming an assured conversationalist.
- To avoid basing action on external validation, you need to find your "authentic voice" and use it.
- Finding your voice requires asking the right questions of yourself.
- There are 3-5 questions that you would generally want to ask people you are talking to.
Sarco assisted suicide pods come in three different styles, and allow you to die quickly and painlessly. They're even quite beautiful to look at.
Death: it happens to everyone (except, apparently, Keanu Reeves). But while the impoverished and lower-class people of the world die in the same ol' ways—cancer, heart disease, and so forth—the upper classes can choose hip and cool new ways to die. Now, there's an assisted-suicide pod so chic and so stylin' that peeps (young people still say peeps, right?) are calling it the "Tesla" of death... it's called... the Sarco!
Swiss researchers identify new dangers of modern cocaine.
- Cocaine cut with anti-worming adulterant levamisole may cause brain damage.
- Levamisole can thin out the prefrontal cortex and affect cognitive skills.
- Government health programs should encourage testing of cocaine for purity.
