In Running, Age Matters Little
Success in running is not just a mental feat, it's physical, too. And the good news is that science backs up the cliché that age doesn't matter, or at least doesn't matter that much.
What's the Latest Development?
Researchers at the German Sports University in Cologne have found that age differences among marathon runners have little influence on how fast they can finish a race. "That might explain in part why the running world is growing, and growing older. The number of runners who finished marathons in the United States, where 7 of the world’s 15 largest races took place last year, increased to 507,000 in 2010 from 25,000 in 1976." Preserving one's athletic ability late into life is generally a question of nutrition, moderation and discipline.
What's the Big Idea?
Contrary to what seems apparent, athletic ability need not drop off dramatically in old age. When it comes to running, having the appropriate gear is almost as important as living healthily. "Arguably the most important tool to keep you running over the years is appropriate shoes." Koen Wilssens, who runs a chain of running shops, "estimates that 50 to 60 percent of people wear the wrong type of running shoe. ... The right shoes won't guarantee you first place, but the wrong shoes guarantee you a short-lived running career."

Can sensitive coral reefs survive another human generation?
- Coral reefs may not be able to survive another human decade because of the environmental stress we have placed on them, says author David Wallace-Wells. He posits that without meaningful changes to policies, the trend of them dying out, even in light of recent advances, will continue.
- The World Wildlife Fund says that 60 percent of all vertebrate mammals have died since just 1970. On top of this, recent studies suggest that insect populations may have fallen by as much as 75 percent over the last few decades.
- If it were not for our oceans, the planet would probably be already several degrees warmer than it is today due to the emissions we've expelled into the atmosphere.
Research has shown that men today have less testosterone than they used to. What's happening?
- Several studies have confirmed that testosterone counts in men are lower than what they used to be just a few decades ago.
- While most men still have perfectly healthy testosterone levels, its reduction puts men at risk for many negative health outcomes.
- The cause of this drop in testosterone isn't entirely clear, but evidence suggests that it is a multifaceted result of modern, industrialized life.
Michael Dowling, Northwell Health's CEO, believes we're entering the age of smart medicine.
- The United States health care system has much room for improvement, and big tech may be laying the foundation for those improvements.
- Technological progress in medicine is coming from two fronts: medical technology and information technology.
- As information technology develops, patients will become active participants in their health care, and value-based care may become a reality.
