ageing brain active

We all know that we should get our exercise. And we all know that this is associated with many positive health outcomes. This includes living longer.

However, we also know that good genes help. We know that some families are long lived. Not only that but we also probably know of some people who seem to have unhealthy, even very unhealthy lifestyles and who seem to live very long lives.

This may suggest that genes are therefore more important than exercise, or physical activity. But is it?

This is the question that a group of researchers set out to answer from the University of California, San Diego.

The researchers around Alexander Posis tracked 5,446 women from 2012 until 2020 and measured their activity with a research-grade accelerometer – and what did they find.

Simple – they found that women with higher levels of light physical activity and moderate to vigorous physical activity had lower risk of death. Those that had higher sedentary time had a higher risk of death. And this was regardless of genetic predisposition.

So, it’s really quite simple. Physical activity will make you live longer irrespective of your genetics. And being sedentary will make you live shorter regardless of your genetics.

Is that enough to get you moving?

Your brain on near-death experiences

Your brain on near-death experiences

Near-death experiences have fascinated many people ever since they have been reported. And these experiences guide our view of how we die: the memories of your life passing in front of your eyes, the tunnel of light, the floating movement towards a bright light....

Social networks grow your brain

The headline is a bit “click baity” but it is what a group of researchers found. To be more specific they found in macaques (cute monkeys) in the wild that having more grooming partners grew different regions of the brain. Grooming is the primate version of having a...

What do creative brains look like?

What do creative brains look like?

We’d probably all be happy to be a bit more creative — though research into our own opinions show that many people do actually consider themselves to be above average in creativity. An obvious self-bias. This is where scientists who study creativity come in and find...

New gender biases discovered

New gender biases discovered

There have been many studies on gender biases, and I have followed, written, and spoken about many of these biases over the years (over a decade actually) but two studies have just come out that caught my eye. One out of New York University focused on gender natural...

Growth of your brain over your life

Growth of your brain over your life

So, we all know that our brain grows very quickly as babies and children and then after a certain age, younger than some of us may like to think, there begins a slow decline. But precisely what and how is the question. Well, this is a question that an international...

How to reduce loneliness

I have reported multiple times on loneliness during the pandemic – mostly because interest and research into loneliness has taken a large uptick. I have also reported on how to combat this and was happy to see that a piece of research just out proved what I had...
