https://borneobulletin.com.bn/the-active-grandparent-hypothesis/ Humans are meant to keep active as we age, according to the "active grandparent" hypothesis put forth by evolutionary researchers [1]. We have a significantly longer lifespan than our close cousins the chimpanzees, who also happen to be considerably more sedentary. One of the study authors, Dr. Daniel Lieberman, observing chimpanzees in the wild … Continue reading We Shouldn’t Take It Easy As We Age →

It has been known for a while that high-fat meals can temporarily impair artery function by causing constriction of the arteries. This is usually demonstrated in the arm (brachial artery) because that is the easiest to measure. It was also made famous in the movie The Gamechangers because it can impair function in an organ … Continue reading Fast Food and Coronary Artery Function →

Last October I mentioned I'd had a urinary tract infection that took a stout round of antibiotics to kick. My urologist suspected benign prostate hyperplasia, a condition where the prostate is restricting the ureter, and was concerned this put me at risk for future UTIs. It's also kind of a nuisance because it often makes … Continue reading Some More Tiny Prosthetic Parts Installed Today →

http://www.Amazon.com/books This was a good book I read recently by Tim Beynon. The title caught my eye because I thought it might be about something akin to runner's high, with the drug being endorphins or endocannabinoids. It is about how running is a major psychological booster for the author, but it is much more, as … Continue reading The Running Drug →

Today I attended "HPV fun day", a special once-a-year event at Hellyer Velodrome. A local couple organizes this, renting the velodrome and then inviting participants to come just try out the velodrome or enter races. I did a little of each. I rode my electric-assist recumbent down the Coyote Creek trail from Morgan Hill to … Continue reading “HPV Fun Day” At Hellyer Velodrome →

My local group rode up into the hills East of Gilroy on a beautiful but windy day. We carpooled to the start, which involved some interesting arranging getting 3 bikes into my friend's van, whose house I'd ridden to. The main ride started at the Mendoza Ranch entrance to Harvey Bear park on Roop road, … Continue reading Up in the East Hills →

https://nutritionfacts.org/video/ultra-processed-junk-food-put-to-the-test/ Dr. Michael Greger's latest nutrition video is about ultra-processed foods, aka junk. It has the astonishing statistic that over 50% of the calories consumed in developed countries come from junk. And when looking at binge eating disorders, pretty much 100% of the calories consumed during a binge are from junk. That rings true for … Continue reading Most People Eating Too Much Junk →

It was raining off and on in the morning so our group ride almost got canceled, but five of us decided to give it a shot anyway. It was a pleasant outing to the foothills East of San Martin and Gilroy. We mostly avoided the rain but it got us a bit right at the … Continue reading Flirting With The Rain in the East Foothills →

I rode my upright to Coyote Valley Open Space and then hiked the Arrowhead trail, which is about 4 miles with some decent climbing. The whole workout was a bit over two hours on a nice spring day. Surprisingly, I set a PR on the hiking loop of 57 minutes, the first time I broke … Continue reading Bike Hiking The Arrowhead Trail →

In my follow-up today with my cardiologist, he gave me surprising news. I have mild to moderate regurgitation in my replacement heart valve, as measured in an echocardiogram. It's not the valve itself that's leaking, it's around the edges where the lining was sewn to the aortic wall. My doc says this sometimes happens shortly … Continue reading Surprising News From Cardiologist →
