A Healthy Brain Needs a Healthy Heart.
The brain is the most demanding organ that your circulatory system has to feed.
Children need exercise. Parents often worry that making time for athletics or even for just playing on the Jungle Jim is going to take away from their kids’ academic achievement. But actually, the opposite is true. There have been analyses of huge numbers of studies that all show that kids who are fit are better in school, get better grades, and have higher intelligence scores than kids who are sedentary. And that is probably because across the lifespan, even into old age, there’s a strong correlation between a healthy heart and a healthy brain.
The brain is the most demanding organ that your circulatory system has to feed. It takes up a lot of the body’s oxygen and a lot of the body’s energy. And unlike most of your tissues, your brain can’t live very long without that blood supply. You cut blood supply off for about five minutes and parts of the brain start dying. So clogged arteries and little clots that cut off blood flow to the brain in older people are a significant source of cognitive difficulty and cognitive deterioration with age. And even in little kids, being physically fit clearly enhances intellectual performance.
The other thing parents should be thinking about is that in childhood your kid needs about 90 minutes a day of active moving around, and parents should really focus, I think, on making sure that that’s fun, first of all. You don’t want to institute exercise as punishment. And you also, I think, want to have them doing something that could potentially continue into adulthood. However much your kids like climbing trees, they’re not going to be doing that when they’re 40, not most of us anyway.
And if you give them a sport or a taste for hiking or a taste for yoga, something that grownups do, you greatly reduce the chance that they’re going to be one of the large numbers of people who are active children who grow into sedentary adults. Usually that transition happens around the age of 13 or so.

Blackstone's Byron Wien, Vice Chairman of Private Wealth Solutions Group, gave a speech laying out the wisdom he learned during his 80 years. Here are 15 of Wien's best life lessons, which teach us about improving our productivity, sleep, burnout avoidance, and everything in between.
According to TwoFold CEO Alison McMahon, a leader who doesn't care (or can't pretend to care) about his or her employees isn't much of a leader at all.
Why do people quit their jobs? Surely, there are a ton of factors: money, hours, location, lack of interest, etc. For Alison McMahon, an HR specialist and the CEO of TwoFold, the biggest reason employees jump ship is that they're tired of working for lousy bosses.
By and large, she says, people are willing to put up with certain negatives as long as they enjoy who they're working for. When that's just not the case, there's no reason to stick around:
Nine times out of ten, when an employee says they're leaving for more money, it's simply not true. It's just too uncomfortable to tell the truth.
Whether that's true is certainly debatable, though it's not a stretch to say that an inconsiderate and/or incompetent boss isn't much of a leader. If you run an organization or company, your values and actions need to guide and inspire your team. When you fail to do that, you set the table for poor productivity and turnover.
McMahon offers a few suggestions for those who want to hone their leadership abilities, though it seems that these things are more innate qualities than acquired skills. For example, actually caring about your workers or not depending wholly on HR thinking they can do your job for you.
It's the nature of promotions that, inevitably, a good employee without leadership skills will get thrust into a supervisory position. McMahon says this is a chronic problem that many organizations need to avoid, or at least make the time to properly evaluate and assist with the transition.
But since they often don't, they end up with uninspired workers. And uninspired workers who don't have a reason to stay won't stick around for long.
