Researchers have discovered evidence that endurance exercise, such as running, swimming, cross-country skiing and cycling, will help you age better than resistance exercise, which involves strength training with weights, as reported in Medical Xpress.
In a study published in the European Heart Journal, researchers in Germany looked at the effects of three types of exercise—endurance training, high intensity interval training and resistance training—on the way cells in the human body age, and they found that endurance and high intensity training both slowed or even reversed cellular aging, but that resistance training did not.

Our DNA is organized into chromosomes in all the cells in our bodies. At the end of each chromosome is a repetitive DNA sequence, called a telomere, that caps the chromosome and protects its ends from deteriorating. As we grow older, the telomeres shorten and this is an important molecular mechanism for cell aging, which eventually leads to cell death when the telomere are no longer able to protect the chromosomal DNA. The process of telomere shortening is regulated by several proteins. Among them is the enzyme telomerase that is able to counteract the shortening process and can even add length to the telomeres.

Here is another source of the same facts I have been reporting in this blog for some years now. Your brain gets as much benefit from your cardiovascular exercise as your body.
Aerobic exercise can improve memory function and maintain brain health as we age, a new Australian-led study has found.
In a first of its kind international collaboration, researchers from NICM and the Division of Psychology and Mental Health at the University of Manchester in the UK examined the effects of aerobic exercise on a region of the brain called the hippocampus, which is critical for memory and other brain functions.
Brain health decreases with age, with the average brain shrinking by approximately five per cent per decade after the age of 40.
Studies in mice and rats have consistently shown that physical exercise increases the size of the hippocampus but until now evidence in humans has been inconsistent. (my emphasis)

I am thrilled to report that today marks the 17th anniversary of my retirement. On October 2 of 2000, I bade the financial world adieu and started my life as a guy who didn’t have to get up for work every day.
I got my first job at the age of 10 sweeping the floor of a dry cleaner and continued to work till I reached 60. Although my degree is in Finance, I went into the publishing world writing and editing. I liked markets, but always knew I would write. I wrote and practiced journalism for most of my career, spending 20 years working for Reuters covering markets and then teaching journalism at the Medill School of Journalism at Northwestern University for several years. Because I had written about markets for 30 years, my boss at a major philanthropy asked me if I would like to manage some money. So, I managed $900 million in bond investments for the final five years of my working life.
No mas. I thought I would celebrate with this biking post. When I was working I used to tell my friends at the office that when I retired I was going to ride my bike on the Chicago lakefront every day. They thought that was funny. I was never more serious.
You all know how I ride my bike nearly every day year ’round here in Chicago. I do it because I love it. Period. Everything else is gravy.
I am always excited to run across items like the ones below. They point to some of the fun I get cycling. If you aren’t doing it, or haven’t done it for a while, think about giving it a spin. You might find that flying across the pavement feels really nice. As you can see from the infographic below, there are some notable physical benefits, too.

Because three out of four cases of osteoporosis are women, most people consider it a women’s disease, especially men. However, as I reported here, after the age of 50 men are as likely to get osteoporosis as prostate cancer. More to the point, older people of both sexes have great vulnerability to it.
Here’s what Harvard Health Publications has to say:
Don’t think men need to worry about osteoporosis? Think again. In fact, about one in four men older than 50 will break a bone due to osteoporosis during their lifetime, according to the National Osteoporosis Foundation.
How can men protect themselves and lower their risk of osteoporosis? Here are some strategies: Continue reading →

We should all be getting exercise on a daily basis. Fully employed folks do that with some difficulty if at all. So, we should definitely get the full benefits from what we are doing on the machines, out there running, or whatever form or activity we have chosen.
Here are some mistakes we make.
